Procedure

17.5 g (70 mmol) of 5-methyl-1,4-dihydropyridine-2,3dicarboxylic acid N-benzylimide are hydrogenated in 150 ml of tetrahydrofuran at 70° C. and under 100 bar over palladium on active charcoal. Then the catalyst is filtered off and the filtrate is concentrated by evaporation. The solid oily residue (13.0 g) is used as a crude product in the next stage.
