Abstract:
The present invention relates to a novel catalytic hydrogenation of substituted 2-methyl cyanopyridyl derivatives, in particular 3-chloro-5-(trifluoromethyl)pyridin-2-yl]acetonitrile [=Py-CN] to substituted 2-ethylaminopyridine derivatives, in particular 2-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]ethanamine [=Py-ethanamine] or salts thereof in the presence of metal catalysts, in particular palladium catalysts.

Claim (Index 1):
A process (B) for production of a compound according to formula (I) wherein p is an integer equal to 1, 2, 3 or 4; each substituent X is chosen, independently of the others, as being halogen, C 1 -C 4  alkyl C 1 -C 4  haloalkyl; q is an integer equal to 1, 2, 3 or 4; each substituent Y is chosen, independently of the others, as being halogen, C 1 -C 4  alkyl or C 1 -C 4  haloalkyl; comprising in (B1) hydrogenating a substituted 2-methyl cyanopyridyl derivative according to formula (II) in the presence of a metal catalyst, an catalyst modifier, and an acid to a substituted 2-ethylaminopyridine derivative according to formula (III) or a corresponding salt thereof, and in (B2) reacting a substituted 2-ethylaminopyridine derivative according to the formula (III) as defined in (B1), with a benzoyl halide according to formula (IV) wherein Hal is fluorine, chlorine or bromine; q is an integer equal to 1, 2, 3 or 4; each substituent Y is chosen, independently of the others, as being halogen, C 1 -C 4  alkyl or C 1 -C 4  haloalkyl; to a compound according to formula (I).
