In analogy to the procedure described for the synthesis of 1-[(3SR,4SR)-1-benzyl-3-(4-chloro-phenyl)-piperidin-4-yl]-ethanone (example 5 (c)) the title compound was prepared from (3S,4R)-1-Benzyl-3-(3,4-difluoro-phenyl)-piperidine-4-carboxylic acid methoxy-methyl-amide and methylmagnesium bromide with subsequent epimerisation with NaOMe in methanol. The title compound was obtained as light brown solid. MS (m/e): 330.3 [(M+H)+].
