PROCESS FOR THE PREPARATION OF 2,2-difluoroethylamine-derivatives by alkylation of 2,2-difluoroethylamine

摘要

A method for preparing a 2,2-difluoroethylamine of the formula (III) in which 2,2-difluoroethylamine of the formula (I) is reacted with a halide of the formula (II) in the presence of a tertiary nitrogen base: where, in the formulae (II) and (III), Hal and A are defined as stated in the description.
