Two methods for the preparation of sitagliptin phosphate: Via chemical resolution and asymmetric hydrogenation

Two effective processes have been developed for the preparation of sitagliptin phosphate. The approach of chemical resolution obtained R-sitagliptin in five steps from commercially available starting materials using the inexpensive NaBH4 to reduce the enamine and then using (-)-di-p-toluoyl-l-tartaric acid to resolve racemates in 11% yield overall. The route successfully avoids the use of expensive noble metal as catalysts compared with traditional synthesis methods, resulting in greatly reduced costs and simplified synthetic routes. Other alternative asymmetric hydrogenation of β-ketomide routes for the synthesis of sitagliptin were found, two of the intermediates were synthesized for the first time. This journal is

PROCESS FOR PREPARATION OF (2R)-4-OXO-4-[3- (TRIFLUOROMETHYL)-5,6-DIHYDRO [1,2,4]-TRIAZOLO[4,3-A]PYRAZIN- 7(8H)-YL]-L-(2,4,5-TRIFLUOROPHENYL)BUTAN-2-AMINE and NEW IMPURITIES IN PREPARATION THEREOF

The present invention relates to synthesis of β-amino acid derivatives of formula (I) and its salts of formula (Ia) by a novel process. The process comprises the reduction of a protected or unprotected prochiral β-amino acrylic acid or derivative there of, by using borane containing reducing agents at atmospheric pressure. The resulting racemic β-amino compound is resolved to a pure stereoisomer of formula (I), specifically to (2R)-4-oxo-4-[3-Ctrifluoromethyl)-5,6-dihydrol[1,2,4]triazolo[4,3-alpyrazin-7(8H)-yl]-1-(2,4,4-trifluorophenyl)butan-2-amine. In an embodiment the invention disclosed polymorphic forms of formula (I), phosphate salt of formula (I) and also a Dibenzoyl-L-tartaric acid salt of formula (I).
