Definitions
- the present invention relates to processes for the preparation of 5-[[2(R)-[l(R)-[3,5-bis(trifluoromethyl)phenyl]ethoxy]-3(S)-(4-fluorophenyl) -4-morpholinyl]methyl]-l,2-dihydro-3H-l,2,4-triazol-3-one, aprepitant,
- U.S. Patent Nos. 5,637,699, 6,096,742, 6,229,010 and 6,297,376 relate to processes of manufacture and the discovery of polymorphic forms of this compound.
- the present invention provides a more practical and economical method for preparing the compound in relatively high yield and purity. As such, there is a need for a process for the preparation of the compound that is cost-effective and utilizes readily available reagents.
- the present invention relates to a process for preparing a compound of formula 1 :
- substance P neurokinin-1 receptor antagonists which are useful, e.g., in the treatment of psychiatric disorders, inflammatory diseases and emesis.
- the present invention relates to a process for preparing a compound of formula 1:
- the process comprises : cyclizing a compound of formula 4:
- the present invention is directed to processes for the preparation of a compound of formula 1 :
- the processes are comprised of:
- (c) cyclizing at a temperature of 140-150°C to produce the compound of formula la.
- the washing step described herein typically uses an aqueous phase, e.g., water, and may optionally contain a salt.
- Representative examples of salts that are useful herein include KCl, KHCO 3 , K 2 CO 3 , Na 2 CO 3 , NaHCO 3 , NaCl and similar such salts.
- KCl is the preferred salt.
- the process is further comprised of a drying step prior to cyclization.
- inorganic base refers to compounds such as sodium carbonate, cesium carbonate, sodium hydroxide, potassium hydroxide, potassium carbonate and the like. More particularly, the preferred inorganic base is potassium carbonate. More particularly, the present invention relates to the process described above wherein compound 2 or 2a is reacted with compound 3 in the presence of an inorganic base, toluene and a polar aprotic solvent.
- polar aprotic solvent refers to a solvent that neither donates or accepts protons, and is, for example, selected from the group consisting of: dimethylformamide (DMF), dimethylsulfoxide (DMSO), N-methylpyrrolidone (NMP), acetonitrile (MeCN), N,N- dimethylacetamide (DM AC) and hexamethylphosphoramide (HMPA).
- DMF dimethylformamide
- DMSO dimethylsulfoxide
- NMP N-methylpyrrolidone
- MeCN acetonitrile
- DM AC N,N- dimethylacetamide
- HMPA hexamethylphosphoramide
- 1,4-oxazine starting material 2 and (2R, 2-alpha-R, 3a)-2-[l-[3,5-bis(trifluoromethyl)- phenyl]ethoxy-3-(4-fluorophenyl)-l,4-oxazine starting material 2a may be obtained in accordance with PCT WO 01/94324 Al (published December 13, 2001) and US 2002/0052494 Al (published May 2, 2002), or using modifications thereof.
- the starting material may be used directly or following purification. Purification procedures include crystallization, distillation, normal phase or reverse phase chromatography. The following example is provided for purposes of illustration and is not intended to limit the disclosed invention.
- the organic layer (containing 4a) was washed with water (5.0 L) at 40°C and then partially concentrated at atmospheric pressure, providing intermediate 4a, which is used in the next step without isolation.
- the resulting solution containing intermediate 4a was heated to 140°C for 3 h and then allowed to cool to RT.
- the solids were filtered and dried in vacuo at 40 °C.
- the product (1.00 kg) was dissolved in methanol (10.0 L) and 50 g of Darco was added. The mixture was heated at 60°C for 1 h and then filtered at this temperature. The filtrates were allowed to cool slowly to RT. Water (5.0 L) was added slowly over 1 h.
