Procedure

The 3,4-dichloro-N-[2-oxocycloheptyl]propionanilide from Part C above is treated with sodium cyanoborohydride and dimethylamine-dimethylamine hydrochloride in methanol in the presence of 3 A molecular sieves; the resulting mixture is worked up under basic pH conditions and the organic residue is chromatographed (column) on silica gel to isolate the cis isomer of 3,4-dichloro-N-[2-(dimethylamino)cycloheptyl]propionanilide.
