| titleOfInvention | Process for the preparation of 2,2-difluoroethylamine derivatives by imine hydrogenation |
| abstract | Process for the preparation of 2,2-difluoroethylamine derivatives, characterized in that 2,2-difluoroethylimine derivatives of general formula (IV) are hydrogenated, giving the corresponding 2,2-difluoroethylamine derivatives of general formula (III):**Formula** in which the radical A in the general formulas (III) and (IV) either represents pyrid-2-yl or pyrid-4-yl or represents pyrid-3-yl, which is optionally substituted in the 6-position with fluorine, chlorine, bromine, methyl, trifluoromethyl or trifluoromethoxy, or represents pyridazin-3-yl, which is optionally substituted in position 6 with chlorine or methyl, or represents pyrazin-3-yl, or represents 2-chloropyrazin- 5-yl, o represents 1,3-thiazol-5-yl, which is optionally substituted in the 2-position by chloro or methyl, o represents pyrimidinyl, pyrazolyl, thiophenyl, oxazolyl, isoxazolyl, 1,2,4- oxadiazolyl, isothiazolyl, 1,2,4-triazolyl or 1,2,5-thiadiazolyl, optionally substituted by fluorine, chlorine, bromine, cyano, nitro, al C1-C4 alkyl (which is optionally substituted by fluorine and/or chlorine), C1-C3 alkylthio (which is optionally substituted by fluorine and/or chlorine) or C1-C3 alkylsulfonyl (which, if case, is substituted with fluorine and/or chlorine), or represents **Formula** in which X represents halogen, alkyl or haloalkyl and Y represents halogen, alkyl, haloalkyl, haloalkoxy, azido or cyano, and R1 and R2 represent , independently of one another, H or C1-C6 alkyl. |
