Therapeutic Use
Noxious chemical, thermal and mechanical stimuli excite peripheral nerve endings of small diameter sensory neurons (nociceptors), deriving from sensory ganglia (e. g., dorsal root, nodose and trigeminal ganglia), which initiate signals that are perceived as pain. Nociceptors are crucial for the detection of harmful or potentially harmful stimuli (e.g., noxious thermal, chemical, and/or mechanical) arising from changes in the extracellular environment during inflammatory, ischemic or otherwise traumatic conditions and that cause or have the potential to cause tissue damage (Wall, P. D., and Melzack, R., Textbook of Pain, 2005, New York: Churchill Livingstone).
Nociceptors transduce noxious stimuli into membrane depolarization that leads to an action potential, its subsequent conduction to the CNS, and ultimately to the perception of pain, discomfort, etc. as well as to certain responses thereto. At the molecular level, nociception is carried out by ion channels and/or receptors. Plant-derived vanilloid compounds (e.g., capsaicin and resiniferatoxin) are known to selectively depolarize nociceptors and elicit sensations of burning pain — the sensation that is typically evoked by capsaicin-containing hot chili peppers. Therefore, capsaicin mimics the action of physiological/endogenous stimuli that activate the "nociceptive pathway". Advances in pain biology have identified a vanilloid receptor, called TRPVl (a.k.a. capsaicin receptor). Because nociceptors are drivers of unwanted pain and inflammatory conditions in human beings and animals, modulation of their function is a validated strategy for palliative and other analgesic therapies.
The compounds of the present invention demonstrate high TRPVl affinity. Accordingly, the present invention is directed to a method for treating a TRPVl ion channel mediated disease in a subject in need thereof comprising administering to the subject an effective amount of a compound of Formula (I). In an example of the invention, the TRPVl ion channel mediated disease is chronic or acute pain due to disease that causes inflammatory pain, burning pain or post-operative pain.
In an example of the invention, the effective amount of the compound of Formula (I) is in a range of from about 0.001 mg/kg/day to about 300 mg/kg/day.
In another example of the invention, the compound of Formula (I) may be used in the manufacture of a medicament for treating a TRPVl ion channel mediated disease, wherein the TRPVl ion channel mediated disease is chronic or acute pain due to disease that causes inflammatory pain, burning pain or post-operative pain. In a related example of the invention, the compound of Formula (I) may also be used as a medicine for treating a TRPVl ion channel mediated disease, wherein the TRPVl ion channel mediated disease is chronic or acute pain due to disease that causes inflammatory pain, burning pain or post-operative pain.
The compounds of Formula (I) may be formulated into pharmaceutical compositions comprising any known pharmaceutically acceptable carriers. Exemplary carriers include, but are not limited to, any suitable solvents, dispersion media, coatings, antibacterial and antifungal agents and isotonic agents. Exemplary excipients that may also be components of the formulation include fillers, binders, disintegrating agents and lubricants. The pharmaceutical compositions of the invention may be administered by any means that accomplish their intended purpose. Examples include administration by parenteral, subcutaneous, intravenous, intramuscular, intraperitoneal, transdermal, buccal or ocular routes. Alternatively or concurrently, administration may be by the oral route. Suitable formulations for parenteral administration include aqueous solutions of the active compounds in water-soluble form, for example, water-soluble salts, acidic solutions, alkaline solutions, dextrose-water solutions, isotonic carbohydrate solutions and cyclodextrin inclusion complexes. An aspect of the use for a compound of Formula (I) includes use of an instant compound as a marker, wherein the compound is labeled with a ligand such as a radioligand (selected from deuterium, tritium and the like).

SCHEME I
Figure imgf000060_0001
Commercially available bromo-diaminobenzene Compound 1-1 is protected, in this instance with a Boc group, to provide a Compound 1-2. Compound 1-2 is then coupled with a suitably substituted phenyl group by a variety of coupling reactions (Suzuki, Stille) that are well known to those versed in the art. A particularly useful method is by a palladium catalyzed cross-coupling Suzuki reaction (see Huff, B. et. al. Org. Syn., 1997, 75: 53-60; and, Goodson, F. E. et. al. Org. Synth., 1997, 75: 61-68).

In this instance, a mixture of Compound 1-2 and a boronic acid or boronate ester Compound 1-3 in sodium carbonate and a catalytic amount of a palladium catalyst in a mixture of dioxane or dimethoxyethane and water or ethanol is heated to 100 0C or more to give an intermediate Compound 1-4.
Suitable palladium catalysts for this reaction include, but are not limited to, a dichloro[l,l '-bis-(diphenylphosphino)ferrocene] palladium (II) dichloromethane adduct [PdCbdppf] and palladium tetrakistriphenylphosphine [Pd(PPh3 )4].
Figure imgf000061_0002
The Compound 1-4 Boc protecting groups are removed under acidic conditions to give a Compound 1-5, which is stirred in a solvent such as ethanol with a halogenated acetimidic acid ethyl ester hydrochloride salt (wherein X represents 2-chloro- or 2-bromo-), prepared according to the procedure described in J. Med. Chem., 1986, 29, 2280) to give a Compound 1-6.
Figure imgf000062_0001
Compound 1-6 is then reacted with H-L-Ai -(R4)r to provide a Compound 1-7 of Formula (I).
For example, to prepare compounds of the present invention wherein L is -Ci_3alkyl-Y- and Y is O, Compound 1-6 is reacted with a solution of an alcohol substituted Ai ring (in a solvent such as acetone) in the presence of a base (such as cesium carbonate) with heating to provide an ether analogue compound of Formula (I).
Figure imgf000062_0002
Compound 1-7 can be reacted with R3X to provide a Compound I-8a and Compound I-8b as a tautomeric mixture. Each isomer may subsequently be obtained using separation techniques known to those skilled in the art.
SCHEME II
Scheme II provides an alternate procedure to produce compounds of the present invention.
Figure imgf000062_0003
Compound 1-1 is reacted with a halogenated acetimidic acid ethyl ester hydrochloride salt (wherein X represents 2-chloro- or 2-bromo-), under conditions described in Scheme I to provide Compound H-I.
Figure imgf000063_0001
As described in Scheme I, Compound II- 1 is reacted with H-L-A1-(K4)T (wherein H is a leaving group) to provide a Compound II-2, which may be carried forward using Suzuki type coupling with a Compound 1-3 to provide Compound 1-7 of Formula (I).

Figure imgf000063_0002
Reaction of an alcohol Compound IH-I with bromoacetonitrile in a solvent such as DMF with sodium carbonate and an equivalent of sodium iodide gives a Compound III-2. Reaction of Compound III-2 with 2N HCl and 1.1 equivalents of ethanol gives a Compound III-3.
Figure imgf000063_0003
Reaction of Compound III-3 with Compound 1-1 in ethanol gives a Compound III-4.
Figure imgf000064_0001
III-5
Reaction of Compound III-4 with a boronic acid or boronate ester Compound 1-3 in sodium carbonate and a catalytic amount of a palladium catalyst in a solvent at a temperature of at least about 100 0C gives a Compound III-5 of Formula (I).
I-5
Figure imgf000064_0002
Compound III-5 can be reacted with R3X to provide a Compound III-6a and Compound III-6b as a tautomeric mixture. Each substantially pure isomer may subsequently be obtained using separation techniques known to those skilled in the art.
Suitable palladium catalysts for this reaction include, but are not limited to, a dichloro [1,1 ' -bis(diphenylphosphino)ferrocene]palladium (II) dichloromethane adduct (PdCbdppf), palladium tetrakistriphenylphosphine [Pd(PPhS)4] and l,l'-[bis(di-tert- butylphosphino)ferrocene] -palladium dichloride [l,r-di(tbpf)-palladium dichloride]. Suitable solvents include, but are not limited to, a mixture of dioxane or dimethoxy ethane and water or ethanol. Protecting groups may be needed at certain stages of the synthesis depending upon substituents and functional groups present on the reactants. Reaction time may be reduced by using a similar or lower temperature in a microwave synthesizer. Microwave accelerated reactions were performed using a Biotage Initiator Microwave Synthesizer. The product of each process step may be separated from the reaction mixture and purified before use as a starting material in a subsequent step. Separation techniques typically include evaporation, extraction, precipitation and filtration. Purification techniques typically include column chromatography (Still, W. C. et. al., J. Org. Chem., 1978, 43, 2921), thin-layer chromatography, crystallization and distillation.
The starting materials and product of each process step may be confirmed by spectroscopic, spectrometric and analytical methods including nuclear magnetic resonance (NMR), mass spectrometry (MS) and liquid chromatography (HPLC).
For preparing compounds of the present invention, common solvents known to those skilled in the art were used such as, but not necessarily limited to: ethyl ether (Et2O), tetrahydrofuran (THF), dioxane, benzene, toluene, hexanes, cyclohexane, dichloromethane (DCM) and dichloroethane (DCE). Compounds of the present invention may be isolated as the acid addition salt and may contain one or more equivalents of the acid. The free base may be obtained by techniques known to those skilled in the art.

Example 1.1
2- [2-(4-trifluoromethyl-phenoxymethyl)- 1 H-benzoimidazol-5 -yl] - benzenesulfonamide (Cpd 1)
The following example provides an alternate preparation of Compound 1. A. (4-trifluoromethyl-phenoxy)-acetonitrile
A 5 -L 3 -neck round bottom flask equipped with a mechanical stirrer, reflux condenser with gas outlet adapter, a Claisen head with a thermocouple and nitrogen inlet adapter, and heating mantle was charged with 4-trifluoromethyl-phenol (225.25 g, 1.39 mol), DMF (1.91 L), followed by NaI (208.3 g, 1.39 mol), Na2CO3 (294.5 g, 2.78 mol), and bromoacetonitrile (214.2 g, 1.76 mol). A modest exotherm to 37 0C was noted. The reaction was warmed to 65 0C for 2 h and the brown suspension was assayed by several methods and judged not to be complete. The reaction was heated to 80 0C for 1 h, when the phenol was found to be absent by HPLC. The reaction was allowed to come to room temperature overnight (14 h). The reaction was diluted with water (2 L), transferred to a 22-L separatory funnel with additional water (6 L) and extracted with a mixture of methyl- t-butylether(MTBE)/ether (2 x 3 L, 2: 1 , then 2 L, 1 :1). The combined organic layers were washed with aqueous HCl (10 %, 2 x 700 mL), aqueous KOH (3 M, 300 mL), water (2 x 700 mL), and brine (2 x 700 mL). The organics were dried (Na2SO4) and filtered though silica gel (500 g), and the silica gel was washed with MTBE/ether (~ 1 L). The organics were concentrated in vacuo and the resulting orange oil transferred to a smaller flask with dichloromethane and MTBE. The concentration was continued under hi-vac (60 torr) at 50 0C and afforded 273.2 g (97.7% isolated yield, residual MTBE by NMR was 0.7% wt/wt) of 2 as an orange oil. 1H-NMR (400 MHz, CD3Cl) δ (ppm) 7.63 (d, 2H) 7.07 (d, 2H) 4.83 (s, 2H). B. 2-(4-trifluoromethyl-phenoxy)-acetimidic acid ethyl ester hydrochloride
A 5 -L 3 -neck round bottom flask equipped with a mechanical stirrer, 1-L pressure- equalizing addition funnel and gas outlet adapter, Claisen head with a thermocouple and nitrogen inlet adapter, in an ice bath, was charged with HCl in ether (2 M, 815 mL) via addition funnel. The addition funnel was replaced with a clean 500-mL addition funnel, and the solution was stirred until the internal temperature was approximately 0 0C. To the addition funnel was added (4-trifluoromethyl-phenoxy)-acetonitrile (neat, 273.0 g, 1.36 mol) followed by ethanol (86.9 mL, 1.49 mol). The solution of (4-trifluoromethyl- phenoxy)-acetonitrile was added drop-wise over 20 min, so not to exceed 2.6 0C. The stirring was continued for 20 min in the ice bath after the addition was complete. The ice bath was removed and the reaction was stirred at room temperature for 6 h. At 15 0C, the orange solution became hazy, followed by sudden precipitation of a thick solid. Once room temperature was achieved, ether (800 mL) was added, a spatula was used to free the solid from the sides of the flask, and the solid was filtered with a Buchner funnel. The yellowish solid became white after washing with ether (500 mL), and the solid was air- dried for 12 h at rt. The collected solid was transferred to an amber bottle and afforded 306.0 g (79.5 % isolated yield, 67 % HPLC purity). 1H-NMR (400 MHz, CD3Cl) δ (ppm) 7.60 (d, 2H, J = 8.8 Hz) 7.18 (d, 2H, J = 8.4 Hz) 5.01 (s, 2H) 4.87 (q, 2H, J = 7.1 Hz) 1.25 (t, 3H, J = 7.0 Hz). C . 5 -bromo-2-(4-trifluoromethyl-phenoxymethyl)- 1 H-benzoimidazole
A 5-L 4-neck round bottom flask equipped with a thermocouple, mechanical stirrer and an argon inlet adapter was charged with 4-bromo-l,2-phenylenediamine (166.4 g, 0.863 mol), ethanol (2 L), followed by the addition of 2-(4-trifluoromethyl-phenoxy)- acetimidic acid ethyl ester hydrochloride (272.0 g, 0.959 mol) and ethanol (0.9 L). The initial solution of diamine turned to a suspension upon the addition of 2-(4-trifluoromethyl- phenoxy)-acetimidic acid ethyl ester hydrochloride, and an exotherm from 17 0C to 28 0C was noted. The reaction was assayed at 2.5 h and found to be complete. The reaction was filtered though Celite (60 g) and the gray solid was washed with ethanol (200 mL) until the filtrates were no longer colored. A clean 12-L 4-neck round bottom flask equipped with a mechanical stirrer, a 1-L addition funnel and ice bath for cooling was set-up and the ethanol filtrates were transferred into the 12-L flask. While cooling the flask, water (3.5 L) was added to the ethanol, and the resulting brown suspension was stirred for 1 h in the ice bath to enhance recovery. The brown solid was filtered evenly between two Buchner funnels, each washed with cold water (150 mL, 2 x 200 niL), and the brown solid was air- dried for a few hours. The brown solid was transferred to two amber bottles, dried in a hi- vac oven (60 mm) at 60 0C, to a constant weight and afforded a total of 331.9 g (103% isolated yield; 97.7-98%, HPLC area%) of the title compound as a brown powder. 1H-NMR (400 MHz, CD3OD) δ (ppm) 7.74 (s, IH) 7.62 (d, 2H, J = 8.0 Hz) 7.50 (d, IH, J = 8.8 Hz) 7.39 (dd, IH, J = 1.6 and 8.4 Hz) 7.23 (d, 2H, J = 8.4 Hz) 5.41 (s, 2H). MS (ESI, pos. ion) m/z: 372.9 (M+ 1).
D. N-tert-butyl-2-[2-(4-trifluoromethyl-phenoxymethyl)-lH-benzoimidazol-5-yl]- benzenesulfonamide
A 12-L 4-neck round bottom flask equipped with a thermocouple, heating mantle, mechanical stirrer, reflux condenser with argon outlet to a bubbler, and an argon inlet adapter was purged with argon for 1 h. Solid Na2CO3 (336.8 g, 3.18 mol) and water (975 mL) were added and the contents stirred until completely dissolved. There was no attempt to control the rise in temperature to 38 0C. To the solution were added 2-(tert-butylamino) sulfonylphenylboronic acid (163.4 g, 0.637 mol), 5-bromo-2-(4-trifluoromethyl- phenoxymethyl)-lH-benzoimidazole (196.6 g, 0.53 mol) and DME (2 L). The argon inlet was removed and the heterogeneous mixture was sparged as vigorously as possible with two pipette -tip argon lines for 1 h. l,r-Di(tbpf)-palladium dichloride (34.5 g, 0.053 mol) was added, the argon inlet replaced, and the reaction was warmed to 61 0C, where it was held for 30 min. Two additional liters of sparged DME was added, and the heating resumed to 78 0C and maintained for 12 h. The heating was turned off (automatically) and the reaction was allowed to cool to room temperature overnight.
The reaction was diluted with water (1.5 L), transferred to a 22-L separatory funnel, and the layers were separated. The top layer (01) was diluted with EtOAc (1 L), and additional separation of an aqueous bottom layer (Al) that resulted was drained with the initial bottom layer (thick with salts). The EtOAc diluted top layer (01) was put aside. The aqueous fraction (Al) was diluted with water (1 L, to dissolve all the salts), returned to the separatory funnel, and extracted with EtOAc (1.5 L). The resulting aqueous layer (A2) was removed and saved for later. The remaining organic layer (02) was combined with the first EtOAc diluted top layer (01) and the combined fraction was washed with water (1.5 L). The resulting aqueous layer (A3) was drained into A2. The remaining organic layer (03) was washed with water (1 L), and the resulting aqueous layer (A4) was drained into A2. The remaining organic layer (04) was washed with aqueous trithiocyanuric acid, trisodium salt (5%, 1 L), and this aqueous layer (A5) was discarded. The remaining organic layer (05) was washed with brine (2 x IL), and the resulting aqueous layer (A6) was saved in A2. The remaining washed organic layer (06) was drained into two 4-L Erlenmeyer flasks and dried (Na2SO4). The combined aqueous A2 layer was returned to the separatory funnel, extracted with EtOAc (1 L) and the resulting organic layer (07) was saved for washing the drying agent and celite later. The dried organic layer (06) was decanted from the drying agent and transferred to a 20-L round bottom flask with Si-thiol functionalized silica gel (Silicycle, 510 g). The drying agent was filtered with Celite, and washed with the EtOAc washing (07) and combined. The organics were swirled on the 20-L rotary evaporator at a bath temperature of 45 0C for 1 h. The silica gel was removed by filtration (sintered glass funnel - golden brown), washed ad lib with EtOAc, and treated again with Si-thiol functionalized silica gel (Silicycle, 510 g) in a 20-L round bottom flask, with swirling at 45 0C for 1 h. The silica gel was removed by filtration (sintered glass funnel - sandy brown), washed ad lib with EtOAc, and the organics were concentrated in vacuo on a large rotary evaporator. The resulting thick oil crystallized in the flask; a minimum amount of EtOAc (1.5 L) was used to redissolve the oil at room temperature. Heptane (1.5 L) was carefully added and the dark solution was transferred to a BIOTAGE column (5 kg, pre-wetted with 8L 2:1 heptane/EtOAc). The column was e luted with 16 L 1 :1 heptane/EtOAc (2-L fractions collected), 16 L 1 :1 heptane/EtOAc (3-L fractions collected), and 16 L 70% EtOAc (2-L fractions collected) in heptane. After evaporation, the product fractions (Bl) (147 g, HPLC: 94.2% purity at 6.853 min, 8.96 min impurity at 3.39%) and (B2) (145 g, 97.9% purity at 6.725 min, with only impurity at 5.95 min, 0.58) were treated separately for recyrstallization.
The Bl product fraction sample (previously transferred to a 3 -L round bottom flask) was dissolved in boiling toluene (-210 mL) and pre-warmed heptane (180 mL) was added until just cloudy. A stir bar was added, the mixture was stirred at room temperature; and within 4-5 min, a thick solid precipitated that was not stirrable. Immediately, a portion of toluene (250 mL) was added using it to transfer the suspension to a 12-L 4-neck round bottom flask equipped with a thermocouple, heating mantle, mechanical stirrer, and reflux condenser. Additional toluene (1100 mL) was added with warming to near reflux (100 0C), enough to completely dissolve the solid. Pre-warmed heptane (1700 mL) was added, followed by the careful addition of more heptane (room temperature, 1200 mL) until the solution was permanently cloudy. The heating mantle was removed, and notice was taken of the oily black film on the bottom of the flask, and the solution was quickly decanted to a clean 12-L 4-neck round bottom flask. However, more globs formed as product oiled out again. The heating mantle was reapplied, toluene (300 mL) was added, the solution was heated to near 100 0C, and most of the oil dissolved (a spatula was used to mechanically remove the oil from the sides of the flask). The mantle was removed and the hazy solution was allowed to cool to room temperature overnight (heavy precipitation was noted around 60 0C). The next day, the solid was filtered from the orange filtrate, and the solid was washed with heptane (2 x 100 mL) that was kept separate from the main filtrate. The product was collected in an amber jar and dried in a hi-vac oven at 55 0C, to afford 90.2 g (35.7% isolated yield; 97.9%, HPLC area%) of the title compound as an off-white solid.
The B2 product fraction sample (previously transferred to a 3 -L round bottom flask) was dissolved in boiling toluene (750 mL) but was not totally clear. Pre-warmed heptane (660 mL) was added, and the mixture was transferred to a 12-L 4-neck round bottom flask equipped with a thermocouple, heating mantle, mechanical stirrer, and reflux condenser. Instant crystallization occurred when stirred; heating was reapplied, and toluene (1.95 L) was added until the solution was clear at near boiling. Warming was continued and pre-warmed heptane (2 L) was added, followed by the careful addition of more heptane (room temperature, 7.7 L) until the additions caused the persistence of a cloud-point (at 93 0C). The heating mantle was removed, and the hazy solution was allowed to cool to room temperature overnight. The next day, an ice bath was applied to enhance the recovery, the solid was filtered from the nearly colorless filtrate, and the solid was washed with heptane (2 x 100 mL), which was kept separate from the main filtrate. The product was collected in an amber jar, dried in a hi-vacuum oven at 40 0C, and afforded 125.3 g (49.5% isolated yield; 98.6%, HPLC area%) of the title compound as a light brown, dense solid. The combined yield was 215.5 g for a combined overall yield of 82%. 1H-NMR (400 MHz, CD3Cl3) δ (ppm) 7.13 (d, IH, J = 7.2 Hz) 7.81 (s, IH) 7.69 (s, IH) 7.57-7.44 (m, 4H) 7.33 (d, 2H, J = 6.8 Hz) 7.03 (s, 2H) 5.43 (s, 2H) 0.95 (s, 9H).

E . 2- [2-(4-trifluoromethyl-phenoxymethyl)- 1 H-benzoimidazol-5 -yl] - benzenesulfonamide
A 5 -L 4-neck round bottom flask equipped with a thermocouple, heating mantle, mechanical stirrer, reflux condenser with gas outlet, and a nitrogen inlet adapter was charged with N-tert-butyl-2-[2-(4-trifluoromethyl-phenoxymethyl)- 1 H- benzoimidazol-5-yl] -benzenesulfonamide (150.0 g, 0.298 mol) and HCl in isopropyl alcohol (IPA) (5-6 M, 2.51 L). The reaction was warmed step-wise with stirring, first to 45 0C, then 60 0C, and finally 72 0C. Heating was continued for 12 h, after which time the heat was turned off, and the reaction allowed to cool to room temperature. HPLC analysis showed there to be about 1.8% of N-tert-butyl-2-[2-(4-trifluoromethyl-phenoxymethyl)- 1 H-benzoimidazol-5 -yl] -benzenesulfonamide remaining. The reaction was chilled in an ice bath to 4 0C, the solid was filtered and washed with IPA (350 mL). The grayish solid (159.2 g) was air-dried for a short while. During this drying, a 22-L 4-neck round bottom flask equipped with a mechanical stirrer was assembled and charged with aqueous sodium bicarbonate (saturated, 3 L) and EtOAc (12 L). The grayish solid was added to the stirred biphasic mixture and within 5 minutes, was completely dissolved. The mixture was transferred to a 22-L separatory funnel and the layers were separated. The aqueous layer (pH 8.5) was discarded. The organic layer was washed with aqueous sodium bicarbonate (saturated, 1 L), brine (half-saturated, 1 L), dried (Na2SO4) between 4 x 4 L Erlenmeyer flasks, and filtered over fresh Na2SO4. The dried EtOAc layer-containing product was placed in a 22-L rotary evaporator flask with Si-thiol functionalized silica gel (Silicycle, 150 g) and swirled in a 45 0C for 1 h. The silica gel was removed by filtration (sintered glass funnel), washed with ad lib EtOAc, and evaporated on a large rotary evaporator. Towards the end of the evaporation, MeCN (1 L) was added to the suspension to assist the azeotropic distillation of residual EtOAc. Evaporation was complete when no liquid distilled at a vacuum of 65 torr. The flask containing the whitish brown solid (125.3 g) was placed in a 22-L heating mantle and carefully heated with MeCN (2200 mL) with the aid of a large paddle stirrer. The completely clear, boiling yellow solution was quickly filtered though a coarse-sintered glass funnel into a 4 L heavy-walled side arm flask. A stir bar was added, the solution was stirred while crystallization ensued and the suspension came to room temperature (approx 2.5 h). The suspension was chilled for 30 min, filtered and washed with MeCN (up to 300 mL). After 15 min air-drying there was afforded 118.0 g (88.5% isolated yield; 98.2-99.5%, HPLC area%) of the title compound as a brilliant white solid. 1H-NMR (400 MHz, CD3C1) δ (ppm) 8.13 (dd, IH, J = 1.2 and 8.4 Hz) 7.77 (d, IH, J = 0.8 Hz) 7.71 (d, IH, 7.6 Hz) 7.66-7.61 (m, 3H) 7.56 (td, IH, J = 1.2 and 8.4 Hz) 7.65 (dd, IH, J = 1.6 and 8.4 Hz) 7.39 (dd, IH, J = 1.6 and 7.6 Hz) 7.27 (d, 2H, J = 8.4 Hz) 5.58 (s, 2H).

Example 1.2
2- [2-(4-trifluoromethyl-phenoxymethyl)- 1 H-benzoimidazol-5 -yl] - benzenesulfonamide disodium salt (Cpd 1)
A 3 -L 1-neck round bottom flask equipped with a wide-mouth funnel was charged with compound 2-[2-(4-trifluoromethyl-phenoxymethyl)-lH-benzoimidazol-5-yl]- benzenesulfonamide (160.1 g, 0.358 mol). Methanol (100 mL) was used to completely wash the material into the flask. A 2-L Erlenmeyer flask was tared on an open-pan balance (+/- 0.1 g) and sodium methoxide in methanol (0.5 M, 1145.0 g) was weighed out, and then poured to the 3 -L round bottom, washing with fresh methanol (150 mL). The flask was attached to a rotary evaporator (no vacuum) and swirled at a bath temperature of 30 0C until the solid had dissolved. The vaccum was carefully applied and the solvent removed in vacuo, with a bath temperature no higher than 38 0C. High vacuum (~20 torr) was applied, and drying was continued at 38 0C for 1 h. The flask was transferred to hi-vac (~20 torr) drying oven, and drying continued at 37 0C for 4 h. The flask was removed, the material was mechanically freed from the sides of the flask, the free-flowing material was poured out of the flask into a large crystallizing dish, and the small lump of MeOH-wet material that remained at the bottom was transferred to a small crystallizing dish. Drying was continued in the hi-vac oven at 43 0C for about 14 h (overnight). Analysis showed both samples in the crystallizing dishes to have the same amount of MeOH (6.3 % wt/wt = 1 equiv MeOH); therefore both were combined in one bottle, which afforded 181.8 g (97% isolated yield; 98.1-99.6%, HPLC area%) of the disdium salt as a slightly off-white solid.

Example 1
Human TRPVl (hTRPVl) binding assay
Compounds of the present invention were tested for their ability to inhibit the binding of [3H] RTX to hTRPVl receptors in a [3H] RTX binding assay as previously described (See, PCT International Application WO02/3341 IAl and Elfrida G.R. et al, J. Pharmacol. Exp. Ther., 2002, 300(1): 9-17.)
HEK293 cells were transfected with hTRPVl vanilloid receptors and washed with Hank's balanced Salt Solution, dissociated with cell dissociation buffer (Sigma), and then centrifuged at 1000 x g for 5 min. Cell pellets were homogenized in cold 20 mM HEPES buffer (pH = 7.4), containing 5.8 mM NaCl, 320 mM sucrose, 2 mM MgCl2, 0.75 CaCl2 and 5 mM KCl and centrifuged at 1000 x g for 15 min. The resultant supernatant was then centrifuged at 40,000 x g for 15 min. The pelleted membranes were stored in a freezer at - 80°C.
Approximately 120 μg protein/ mL from membranes were incubated with indicated concentrations of [3H]RTX in 0.5 mL of the HEPES buffer (pH 7.4) containing 0.25 mg/mL fatty acid-free bovine serum albumin at 37 0C for 60 min. The reaction mixture was then cooled to 4°C, and 0.1 mg of αi-acid glycoprotein was added to each sample, which was then incubated at 4°C for 15 min. The samples were centrifuged at 18,500 x g for 15 min. The tip of the microcentrifuge tube containing the pellet was cut off. Bound radioactivity was quantified by scintillation counting. Non-specific binding was measured in the presence of 200 nM unlabeled RTX.
Alternatively, a binding assay using rat tissue was used. Rat spinal cord was homogenized twice with a Polytron and centrifuged at 3000 rpm for 10 min in 20 mM HEPES buffer (pH = 7.4), containing 5.8 mM NaCl 5.8, 320 mM sucrose, 2 mM MgCl2, 0.75 mM CaCl2 0.75 and 5 mM KCl. The supernatant was then centrifuged at 40,000 x g for 15 min. The pellet was saved in a tube, and 10 mL of assay buffer were added into the tube. The pellet and buffer were mixed with a Polytron. The assay contained 120 μg/mL membrane protein and 0.3-0.6 nM [ H]-RTX (Perkin-Elmer, Boston) in a total volume of 0.5 niL HEPES buffer. Following incubation for 60 min at 37 C, the samples were cooled on ice, and 0.1 mg of αi-acid glycoprotein were added into the samples. After centrifugation at 18,500 x g for 15 min, the supernatant was aspirated and the tips of tubes were cut off and placed into 6 mL vials. Data were calculated according to the equation: % inhibition = 100% x [(total binding-binding)/(total binding-non specific binding)]. K1 values were calculated using a Prism program.
Compound 1 was tested and found to provide a K1 value of 2.7 nM.
Example 2 Human TRPVl (hTRPVl) functional assay
The functional activity of the test compounds was determined by measuring changes in intracellular calcium concentration using a Ca++-sensitive fluorescent dye and FLIPR™ technology. Increases in Ca++ concentration were readily detected upon challenge with capsaicin. HEK293 cells expressing hTRPVl were grown on poly-D-lysine coated 384 well black-walled plates (BD 354663) and 1 day later loaded with Calcium 3 Dye for 35 min at 37°C, 5% CO2 and then for 25 min at room temperature, and subsequently tested for agonist-induced increases in intracellular Ca2+ levels using FLIPR™ technology. Cells were challenged with test compounds (at varying concentrations) and intracellular Ca2+ was measured for 5 min prior to the addition of capsaicin to all wells to achieve a final concentration of 0.030 μM eliciting -80% maximal response.
EC50 or IC50 values were determined from concentration-response studies, which were generated using the average of quadruplicate wells for each data point. For those compounds tested, IC50 and percent inhibition values are shown in Table 1. The symbol "a" represents percent inhibition obtained at a test concentration of 0.5 μm; the symbol "b" represents percent inhibition obtained at a test concentration of 0.2 μm; the symbol "c" represents an IC50 value (nM) derived from a variety of test concentrations. The term "NA" means that the result is not applicable for a particular compound. Table 1

Chemically-Induced Models Of Inflammatory Pain
Compounds of the present invention were tested in animal models of inflammation and inflammatory pain. To assess the ability of test compounds to reverse thermal hyperalgesia, baseline response latencies on a radiant heat (RH) paw stimulator were obtained before an intraplantar injection of 100 μL (1 μg/μL) CFA (1:1 CFA:saline) in male Sprague-Dawley rats. Only withdrawal responses that were quick hind paw movements (with or without licking of the hind paw) were recorded. Paw movements associated with locomotion or a shifting of weight were not considered a withdrawal response. The stimulus intensity that produced 10-15 sec baseline withdrawal latencies was used and a maximum cutoff of 20 sec was imposed. Hypersensitivity was evaluated 24 h after CFA. Only rats that exhibited at least a 25 % reduction in response latency from baseline (i.e. hyperalgesia) were included in further analysis. Following the post-inflammogen latency assessment, rats were orally dosed (2.5 mL/kg) with test compound (10 mg/kg) or vehicle (20 % hydroxypropyl beta cyclodextran). To determine the time of peak effect, latencies were redetermined 30, 60, 100, 180 and 300 min after compound administration.
Data are presented as the maximal percent reversal of hypersensitivity obtained during the 300 min test, which was calculated for each animal according to the formula:
% reversal = 100% x (treatment response - post-inflammogen response) / (pre- inflammogen response - post-inflammogen response)
