BACKGROUND
[0002] N-((R)-2,3-dihydroxypropoxy)-3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-benzamide ("mirdametinib", or "PD-0325901") is a small molecule drug which has been designed to inhibit mitogen-activated protein kinase kinase 1 ("MEK1") and mitogen-activated protein kinase kinase 2 ("MEK2"). MEK1 and MEK2 are proteins that play key roles in the mitogen-activated protein kinase ("MAPK") signaling pathway. The MAPK
pathway is critical for cell survival and proliferation, and overactivation of this pathway has been shown to lead to tumor development and growth. Mirdametinib is a highly potent and specific allosteric non-ATP-competitive inhibitor of MEK1 and MEK2.
By virtue of its mechanism of action, mirdametinib leads to significantly inhibited phosphorylation of the extracellular regulated MAP kinases ERK1 and ERK2, thereby leading to impaired growth of tumor cells both in vitro and in vivo. In addition, evidence indicates that inflammatory cytokine-induced increases in MEK/ERK activity contribute to the inflammation, pain, and tissue destruction associated with rheumatoid arthritis and other inflammatory diseases.
100031 Crystal forms of N-((R)-2,3-dihydroxypropoxy)-3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-benzamide have been described previously. W02002/006213 describes crystalline Forms land II. U.S. Patent No. 7,060,856 ("the '856 patent") describes a method of producing Form IV. The '856 patent indicates that the material produced by this method was greater than 90% Form IV (The '856 patent, Example 1). The '856 patent also states that the differential scanning calorimetry ("D SC") of the material produced shows an onset of melting at 110 C, as well as a small peak with an onset at 117 C, consistent with the material being a mixture of two forms.
[0004] WO 2006/134469 ("the '469 PCT publication") also describes a method of synthesizing N#R)-2,3-dihydroxypropoxy)-3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-benzamide. The '469 PCT publication reports the method yields a product conforming to the polymorphic Form IV disclosed in U.S. Patent Application No.
10/969,681 which issued as the '856 patent.
[0005] Compositions containing more than one polymorphic form are generally undesirable because of the potential of interconversion of one polymorphic form to another. Polymorphic interconversion can lead to differences in the effective dose or physical properties affecting processability of a drug, caused by differences in solubility or bioavailability. Thus, there is a need for a composition containing essentially pure Form IV of N-((R)-2,3-dihydroxypropoxy)-3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-benzamide, for use in treatment of a tumor, a cancer, or a Rasopathy disorder.

[0105] Recognizing that triflate gave the highest yield, the possibility of eliminating the cryogenic conditions was investigated, set possibly due to stability concerns of the "methanesulfonate" intermediate. The following experiments suggest no significant yield loss for experiments run at -20 C.

[0106] The data presented above suggest no detrimental effect was observed after prolonged stirring of the "trifluoromethane sulfonate" intermediate prior to the N-hydroxyphthalimide addition. Reverse addition of intermediate mixture to solid NHP
appears to give the highest yield.
[0107] An additional advantage of the triflate usage was easy removal of the Et3N triflate salts side product simply by water wash. This resulted in highly pure N-hydroxyphthalimide-protected alcohol, IPGAP (PD-0333760) in Toluene, which can be isolated as crystals or carried through to the final deprotection reaction.
[0108] Both aqueous and anhydrous ammonia base were examined as deprotecting agents. The results were both successful. The phthalimide side product was simply filtered out from solution of product (PD-0337792) in toluene when anhydrous ammonia was used. Similarly, it was filtered out from the solution after performing azeotropic water removal from toluene when aqueous ammonia (28% solution) was used.
Anhydrous ammonia however, requires the reaction to be performed at high-pressure containment.
Experiments conducted by sparging the ammonia gas gave acceptable yields;
however, they required large volumes and use of a cryogenic condenser (to avoid gas from escaping the reactor headspace).

*from PD-0333760 Step 2: Fluoride Displacement [0109] Examination of the reaction in an automated reactor reveals that the reaction is essentially dosed-controlled after the initiation period. Increasing the amount of lithium amide and increased agitation rate appear to shorten the induction time. The addition of water was shown to prolong the induction time. However, it is not clear whether it is due to lithium hydroxide formation.
[0110] Induction time is increased when 0.1 equivalent H20 was added. The trend was reversed however when 0.1 equivalent lithium hydroxide was added. Induction times were decreased upon increasing lithium amide equivalents and agitation.

The development focus of this step was to ensure that impurity levels are within the specification limit. The known impurities in the final isolated diol product are excess PD-0315209 acid, dimeric impurities and chiral impurities. The chiral impurities are controlled by limiting the R-enantiomer in the starting s-glycerol acetonide.
Elevated levels of dimeric impurity (d) has been known to cause difficulties in the polymorph transformation step. The dimeric impurity is formed initially by the reaction of imidazole (CDT-activated acid) in the presence of excess acid PD-0315209 forming dimer (a) and possibly (b) which are then carried through in the subsequent IPGA coupling and acid hydrolysis steps forming dimer (c) and (d), respectively. Impurity d is referred to as PF-00191189.

None of the solids is initially soluble in acetonitrile. The acid activation reaction was fast (almost instantaneous), forming highly soluble imidazolide product that turned the slurry into a clear homogenous solution while CO2 gas evolution occurs.
[0113] Lab experiments generally resulted in impurity levels under 3%, which can be completely removed by the subsequent recrystallization from a 3-5% ethanol-toluene system. An additional recrystallization was performed in the few instances where the impurity level was above 0.3%. Table 4 shows selected results of lab experiments where elevated levels of impurities were observed and how they were removed in the subsequent recrystallization. The crude PD-0325901 was obtained using the acetonitrile/toluene system and the purified product was recrystallized from a 5%
ethanol/toluene system. Entries no. 4 and 5 used additional solvent to ensure impurity removal with entry 5 requiring two recrystallizations in order to achieve a level of "ND"
in the polymorph transformation. The 8-10 ml/g crude crystallization volume was chosen to limit product loss while maintaining a filterable slurry and ensuring removal of impurities.

[0114] A scale up procedure that would give tolerable levels of impurities prior to the polymorph transformation (<0.3%), without losing too much product in the recrystallization was developed considering the solid CDI addition rate. Fast addition is preferred to minimize impurity formation; however, the addition needs to be performed at a rate that ensures safely venting of the evolved CO2.
[0115] A half portion of solid CDI was initially added to the PD-0325901 acid, followed by solvent addition. The remaining CDI was added then through a hopper in less than 30 minutes to ensure that the impurity levels were below 3%.
Polymorph Transformation [0116] Three polymorphic forms of PD-0325901 are characterized below. Form I has the highest melting point (-117 C) and is enantiotropically related to Form IV
(m.p. 112 C), which is the more stable form below the estimated transition temperature of 73 C. Form II is the low melting form (m.p. ¨ 85 C).
Table 5: Crystal Forms Melting Points and Heat of Fusions Melting Point, Heat of Fusion, DHf oc (J/g) Form I 117 85 Form II 90 70 Form IV 112 94 [0117] Most of the polymorph transformation experiments were performed using highly pure PD-0325901 containing various forms and generally exhibited a low melting point below 80 C as the results of an efficient Et0H/Toluene recrystallization following the crude crystal isolation directly from the reaction mixture. These various polymorphs were completely dissolved in Et0H and subsequently precipitated by adding water (20 volumes) in a 15-to-60 minute period at 20-25 C. Analysis of the solids sampled at less than 2 hours stirring show complete polymorph transformation to Form IV. The only failure occurred when water was added almost immediately in one portion to a solution of PD-0325901 in Et0H (4 vol.). In this case, the undesired polymorph Form I was obtained exclusively.
[0118] One anomaly in the standard procedure was observed. One lot produced mixed polymorphs but had no detectable level of impurity after recrystallization.
The corrective procedure for this case includes transforming the low melting forms (Form II) to all Form I at temperatures close to or above 73 C followed by a slow (-4 h period) cooling to 20 C.
[0119] The Et0H/Water system produces an efficient polymorph transformation. The recrystallized (purified) PD-0325901, which initially consisted of enantiotropic polymorphs Form I (m.p. ¨117 C) and Form IV (m.p. ¨112 C) was completely transformed to Form IV.
Pilot Plant Preparation of Essentially Pure Form IV
Step 1: Preparation of "Side Chain", PD-0337792 [0120] 14.4 kg alcohol (chemical purity 99.4%, optical purity 99.6%
enantiomeric excess) was converted to 97.5 kg 9.7% w/w PD-0337792 (IPGA) solution in toluene (overall yield ¨60%). The triflate activation was performed in the 200 L
reactor by maintaining temperatures under -20 C during triflic anhydride addition. The resulting activated alcohol was then transferred to a 400 L reactor containing solid N-hydroxypthalimide (NHP) and the reaction was allowed to occur at ambient temperature to completion. The final base de-protection was performed by adding aqueous ammonia (-28% soln, 5 equiv., 34 kg). After reaction completion, water was removed by distillation from toluene, and the resulting solid side product was filtered out to yield the product solution.
Step 2: Preparation of PD-0315209 [0121] The process yielded 21.4 kg (99.4% w/w assay), which is 80% of theoretical from starting materials 2,3,4-trifluorobenzoic acid (12 kg, 1 eq.) and 2-fluoro-4-iodoaniline (16.4 kg, 1.02 eq.) with lithium amide base (5 kg, 3.2 eq.). The reaction was initiated by adding 5% of total solution of TFBA and FIA into lithium amide slurry at 50 C. This reaction demonstrated a minimal initiation period of ¨10 minutes, which was observed by color change and slight exotherm. The remaining TFBA/FIA solution in THF was slowly added through a pressure can in an hour while maintaining the reaction temperatures within 45-55 C. There was no appreciable pressure rise (due to ammonia gas release) observed during the entire operation.
Step 3: Preparation of PD-0325901 [0122] A modification was made to the CDI charging to mitigate potential gas generation. Two equal portions of CDI were added into solid FIPFA before and after solvent addition (through a shot loader). The timing between the two solid CDI
additions (4.6 kg each) should not exceed 30 minutes. Then two intermediate filter cakes were dissolved with ethanol. The excess ethanol was distilled and replaced with toluene to approximately 5% v/v ethanol prior to PD-0325901 recrystallization. Lab studies suggested that the crystallization from toluene and acetonitrile and recrystallization from ethanol in toluene would not be able to reduce impurities which is essential for the polymorph transformation. The presence of a dimeric impurity (PF-00191189) at a level greater than 0.2% has been known to result in the formation of undesired polymorph.

la lel Exact Mass: 856.93 [0123] The crude crystallization from the final reaction mixture reduced dimeric impurity PF-00191189 to approximately 1.9% and the subsequent recrystallization further reduced it to approximately 0.4%. As a consequence, undesired polymorphs were produced. The DSC patterns indicated two different melting points ¨80 C (low melt Form II) and ¨117 C (Form I). Also during the processing, the solids crystallized at a much lower temperature than expected (actual ¨10 C, expected ¨40 C). It is suspected that the unsuccessful recrystallization is due to a change in the solvent composition as a result of incomplete drying of the crude. Drying of the crude wet cake prior to ethanol dissolution was stopped after about 36 hours when the crude product was ¨28 kg (26 kg theoretical).
Polymorph Transformation [0124] Approximately 7.4 kg of PD-0325901 (mixed polymorphs) from the final Et0H/Water crystallization and precipitated materials from the earlier Et0H/Toluene filtrate were taken forward to the polymorph transformation. Both crops were separately dried in the filter until constant weights and each was dissolved in Et0H. The combined Et0H solution was analyzed by HPLC and resulted in an estimated amount of 16.4 kg PD-0325901. The recrystallization was started after removing Et0H via vacuum distillation and adjusting the solvent composition to about 5% Et0H in Toluene at 65 C
(i.e., Et0H is added dropwise at 65 C until complete solids dissolution).
[0125] A slow 4-hour cooling ramp to 5 C followed by 12 h stirring was performed to ensure satisfactory results. The resulting slurry was filtered and again it was completely dried in the filter until constant weight (approximately 3 days). The purified solid showed 99.8% pure PD-0325901 with not detected level of dimeric impurity PF-00191189.
[0126] The dried solid (15.4 kg) was re-dissolved in exactly 4 volumes of Et0H (62 L) off of the filter, transferred to the reactor and precipitated by a slow (-3 h) water addition (308 L) at 30-35 C, cooled to 20 C and stirred for 12 h. The DSC analysis of a slurry sample taken at 2 h shows the solids to be completely Form IV (desired polymorph).
[0127] 21.4 kg PD-0315209, 9.7 kg CDI (1.05 equiv.), 91 kg solution of 9.7% PD-0337792 in Toluene (1.1 equiv.) were used and resulted in 12.74 kg of PD-(assay 99.4%, 100% Form IV, Yield ¨ 48%).

Identification of PD-0325901 is performed by obtaining either an infrared or proton NMR spectrum, in addition to the HPLC retention time. For purity evaluation, process impurities and degradants are identified by their characteristic relative retention times and quantitated by area normalization.

However, the crystal yielded Form IV with the same XRPD characteristics as Form IV
prepared by the method of Example 1, and was therefore of suitable purity for Form IV

[0105] Recognizing that triflate gave the highest yield, the possibility of eliminating the cryogenic conditions was investigated, set possibly due to stability concerns of the "methanesulfonate" intermediate. The following experiments suggest no significant yield loss for experiments run at -20 C.

[0106] The data presented above suggest no detrimental effect was observed after prolonged stirring of the "trifluoromethane sulfonate" intermediate prior to the N-hydroxyphthalimide addition. Reverse addition of intermediate mixture to solid NHP
appears to give the highest yield.
[0107] An additional advantage of the triflate usage was easy removal of the Et3N triflate salts side product simply by water wash. This resulted in highly pure N-hydroxyphthalimide-protected alcohol, IPGAP (PD-0333760) in Toluene, which can be isolated as crystals or carried through to the final deprotection reaction.
[0108] Both aqueous and anhydrous ammonia base were examined as deprotecting agents. The results were both successful. The phthalimide side product was simply filtered out from solution of product (PD-0337792) in toluene when anhydrous ammonia was used. Similarly, it was filtered out from the solution after performing azeotropic water removal from toluene when aqueous ammonia (28% solution) was used.
Anhydrous ammonia however, requires the reaction to be performed at high-pressure containment.
Experiments conducted by sparging the ammonia gas gave acceptable yields;
however, they required large volumes and use of a cryogenic condenser (to avoid gas from escaping the reactor headspace).

*from PD-0333760 Step 2: Fluoride Displacement [0109] Examination of the reaction in an automated reactor reveals that the reaction is essentially dosed-controlled after the initiation period. Increasing the amount of lithium amide and increased agitation rate appear to shorten the induction time. The addition of water was shown to prolong the induction time. However, it is not clear whether it is due to lithium hydroxide formation.
[0110] Induction time is increased when 0.1 equivalent H20 was added. The trend was reversed however when 0.1 equivalent lithium hydroxide was added. Induction times were decreased upon increasing lithium amide equivalents and agitation.

The development focus of this step was to ensure that impurity levels are within the specification limit. The known impurities in the final isolated diol product are excess PD-0315209 acid, dimeric impurities and chiral impurities. The chiral impurities are controlled by limiting the R-enantiomer in the starting s-glycerol acetonide.
Elevated levels of dimeric impurity (d) has been known to cause difficulties in the polymorph transformation step. The dimeric impurity is formed initially by the reaction of imidazole (CDT-activated acid) in the presence of excess acid PD-0315209 forming dimer (a) and possibly (b) which are then carried through in the subsequent IPGA coupling and acid hydrolysis steps forming dimer (c) and (d), respectively. Impurity d is referred to as PF-00191189.

None of the solids is initially soluble in acetonitrile. The acid activation reaction was fast (almost instantaneous), forming highly soluble imidazolide product that turned the slurry into a clear homogenous solution while CO2 gas evolution occurs.
[0113] Lab experiments generally resulted in impurity levels under 3%, which can be completely removed by the subsequent recrystallization from a 3-5% ethanol-toluene system. An additional recrystallization was performed in the few instances where the impurity level was above 0.3%. Table 4 shows selected results of lab experiments where elevated levels of impurities were observed and how they were removed in the subsequent recrystallization. The crude PD-0325901 was obtained using the acetonitrile/toluene system and the purified product was recrystallized from a 5%
ethanol/toluene system. Entries no. 4 and 5 used additional solvent to ensure impurity removal with entry 5 requiring two recrystallizations in order to achieve a level of "ND"
in the polymorph transformation. The 8-10 ml/g crude crystallization volume was chosen to limit product loss while maintaining a filterable slurry and ensuring removal of impurities.

[0114] A scale up procedure that would give tolerable levels of impurities prior to the polymorph transformation (<0.3%), without losing too much product in the recrystallization was developed considering the solid CDI addition rate. Fast addition is preferred to minimize impurity formation; however, the addition needs to be performed at a rate that ensures safely venting of the evolved CO2.
[0115] A half portion of solid CDI was initially added to the PD-0325901 acid, followed by solvent addition. The remaining CDI was added then through a hopper in less than 30 minutes to ensure that the impurity levels were below 3%.
Polymorph Transformation [0116] Three polymorphic forms of PD-0325901 are characterized below. Form I has the highest melting point (-117 C) and is enantiotropically related to Form IV
(m.p. 112 C), which is the more stable form below the estimated transition temperature of 73 C. Form II is the low melting form (m.p. ¨ 85 C).
Table 5: Crystal Forms Melting Points and Heat of Fusions Melting Point, Heat of Fusion, DHf oc (J/g) Form I 117 85 Form II 90 70 Form IV 112 94 [0117] Most of the polymorph transformation experiments were performed using highly pure PD-0325901 containing various forms and generally exhibited a low melting point below 80 C as the results of an efficient Et0H/Toluene recrystallization following the crude crystal isolation directly from the reaction mixture. These various polymorphs were completely dissolved in Et0H and subsequently precipitated by adding water (20 volumes) in a 15-to-60 minute period at 20-25 C. Analysis of the solids sampled at less than 2 hours stirring show complete polymorph transformation to Form IV. The only failure occurred when water was added almost immediately in one portion to a solution of PD-0325901 in Et0H (4 vol.). In this case, the undesired polymorph Form I was obtained exclusively.
[0118] One anomaly in the standard procedure was observed. One lot produced mixed polymorphs but had no detectable level of impurity after recrystallization.
The corrective procedure for this case includes transforming the low melting forms (Form II) to all Form I at temperatures close to or above 73 C followed by a slow (-4 h period) cooling to 20 C.
[0119] The Et0H/Water system produces an efficient polymorph transformation. The recrystallized (purified) PD-0325901, which initially consisted of enantiotropic polymorphs Form I (m.p. ¨117 C) and Form IV (m.p. ¨112 C) was completely transformed to Form IV.
Pilot Plant Preparation of Essentially Pure Form IV
Step 1: Preparation of "Side Chain", PD-0337792 [0120] 14.4 kg alcohol (chemical purity 99.4%, optical purity 99.6%
enantiomeric excess) was converted to 97.5 kg 9.7% w/w PD-0337792 (IPGA) solution in toluene (overall yield ¨60%). The triflate activation was performed in the 200 L
reactor by maintaining temperatures under -20 C during triflic anhydride addition. The resulting activated alcohol was then transferred to a 400 L reactor containing solid N-hydroxypthalimide (NHP) and the reaction was allowed to occur at ambient temperature to completion. The final base de-protection was performed by adding aqueous ammonia (-28% soln, 5 equiv., 34 kg). After reaction completion, water was removed by distillation from toluene, and the resulting solid side product was filtered out to yield the product solution.
Step 2: Preparation of PD-0315209 [0121] The process yielded 21.4 kg (99.4% w/w assay), which is 80% of theoretical from starting materials 2,3,4-trifluorobenzoic acid (12 kg, 1 eq.) and 2-fluoro-4-iodoaniline (16.4 kg, 1.02 eq.) with lithium amide base (5 kg, 3.2 eq.). The reaction was initiated by adding 5% of total solution of TFBA and FIA into lithium amide slurry at 50 C. This reaction demonstrated a minimal initiation period of ¨10 minutes, which was observed by color change and slight exotherm. The remaining TFBA/FIA solution in THF was slowly added through a pressure can in an hour while maintaining the reaction temperatures within 45-55 C. There was no appreciable pressure rise (due to ammonia gas release) observed during the entire operation.
Step 3: Preparation of PD-0325901 [0122] A modification was made to the CDI charging to mitigate potential gas generation. Two equal portions of CDI were added into solid FIPFA before and after solvent addition (through a shot loader). The timing between the two solid CDI
additions (4.6 kg each) should not exceed 30 minutes. Then two intermediate filter cakes were dissolved with ethanol. The excess ethanol was distilled and replaced with toluene to approximately 5% v/v ethanol prior to PD-0325901 recrystallization. Lab studies suggested that the crystallization from toluene and acetonitrile and recrystallization from ethanol in toluene would not be able to reduce impurities which is essential for the polymorph transformation. The presence of a dimeric impurity (PF-00191189) at a level greater than 0.2% has been known to result in the formation of undesired polymorph.

la lel Exact Mass: 856.93 [0123] The crude crystallization from the final reaction mixture reduced dimeric impurity PF-00191189 to approximately 1.9% and the subsequent recrystallization further reduced it to approximately 0.4%. As a consequence, undesired polymorphs were produced. The DSC patterns indicated two different melting points ¨80 C (low melt Form II) and ¨117 C (Form I). Also during the processing, the solids crystallized at a much lower temperature than expected (actual ¨10 C, expected ¨40 C). It is suspected that the unsuccessful recrystallization is due to a change in the solvent composition as a result of incomplete drying of the crude. Drying of the crude wet cake prior to ethanol dissolution was stopped after about 36 hours when the crude product was ¨28 kg (26 kg theoretical).
Polymorph Transformation [0124] Approximately 7.4 kg of PD-0325901 (mixed polymorphs) from the final Et0H/Water crystallization and precipitated materials from the earlier Et0H/Toluene filtrate were taken forward to the polymorph transformation. Both crops were separately dried in the filter until constant weights and each was dissolved in Et0H. The combined Et0H solution was analyzed by HPLC and resulted in an estimated amount of 16.4 kg PD-0325901. The recrystallization was started after removing Et0H via vacuum distillation and adjusting the solvent composition to about 5% Et0H in Toluene at 65 C
(i.e., Et0H is added dropwise at 65 C until complete solids dissolution).
[0125] A slow 4-hour cooling ramp to 5 C followed by 12 h stirring was performed to ensure satisfactory results. The resulting slurry was filtered and again it was completely dried in the filter until constant weight (approximately 3 days). The purified solid showed 99.8% pure PD-0325901 with not detected level of dimeric impurity PF-00191189.
[0126] The dried solid (15.4 kg) was re-dissolved in exactly 4 volumes of Et0H (62 L) off of the filter, transferred to the reactor and precipitated by a slow (-3 h) water addition (308 L) at 30-35 C, cooled to 20 C and stirred for 12 h. The DSC analysis of a slurry sample taken at 2 h shows the solids to be completely Form IV (desired polymorph).
[0127] 21.4 kg PD-0315209, 9.7 kg CDI (1.05 equiv.), 91 kg solution of 9.7% PD-0337792 in Toluene (1.1 equiv.) were used and resulted in 12.74 kg of PD-(assay 99.4%, 100% Form IV, Yield ¨ 48%).

However, the crystal yielded Form IV with the same XRPD characteristics as Form IV
