NEW EFFICIENT PROCESS FOR THE PREPARATION OF SITAGLIPTIN.

Object of the present invention is an efficient process for the preparation of the active pharmaceutical ingredient Sitagliptine and the 2,4,5-trifluorophenylacetic acid (TFAA) and salt thereof, which is a key intermediate for the synthesis of Sitagliptine. (I)

Process for the preparation of fluorinated benzoic acids

A process for the preparation of 2-chloro-4,5-difluorobenzoic acid and 2,4,5-trifluorobenzoic acid as well as synthetic intermediates useful in and prepared according thereto, comprising reacting a nitrobenzene having the formula STR1 wherein X is chloro or fluoro, with an appropriate carbanion to form a compound having the formula STR2 wherein one of Y and Z is chloro and the other is nitro, and R is a radical selected from the group consisting of --CCl3, --CH2 NO2, --CH(NO2)R1, --CH(CO2 R1)2, --CH(C(O)R2)2, --CH(CN)CO2 R1, --CH(CO2 R1)COR2 and --COR2 where R1 is alkyl or arylalkyl and R2 is alkyl, aryl or arylalkyl and, where appearing more than once in such a radical, R1 and R2 may be the same or different at each occurrence.

Novel intermediates for the production of 2,4,5-trifluorobenzoyl fluoride

The present invention comprises compounds of the formulas: STR1 wherein X is Cl or Br. These compounds are useful as intermediaries for the production of 2,4,5-trifluorobenzoic acid and 2,4,5-trifluorobenzoyl fluoride.

2,3,4,5-tetrahalogenobenzene derivatives

2,3,4,5-trihalogenobenzene derivatives of the formula STR1 in which R is --COOH, --COCl, --COF, --CN, --CONH2, --CH2 OH, --CH2 Cl, --CHCl2, --CCl3 or --CHO, R1 is H, Cl or F, and R2 is Cl or F, it only being possible for R1 or R2 to be F, and processes for their preparation starting from benzonitriles reacted with potassium fluoride. The novel compounds are intermediates for antibacterials such as quinolone carboxylic acids.
