A solution of 19 g of N-[1-(phenylmethyl)4-methyl-4-piperidinyl]acetamide hydrochloride in 400 ml of methanol was hydrogenated at normal pressure and at room temperature with 5 g of palladium-on-charcoal catalyst 10%. After the calculated amount of hydrogen was taken up, the catalyst was filtered off and the filtrate was evaporated, yielding 11.8 g of N-[4-methyl-4-piperidinyl]acetamide hydrochloride; mp. 230°-233° C. (interm. 3).
