Versuchsvorschrift

Following the procedure of Example 4, a mixture of 201 parts (1 mole) of N-(1,1-dimethyl-3-oxobutyl)-3-methoxypropionamide, 170 parts (2 moles) of piperidine, 0.5 part of platinum oxide and 1 part of dimethylammonium perchlorate is hydrogenated in the Parr apparatus, starting at a pressure of 70 psi. and recharging when the pressure has reached 39 psi. After workup as described in Example 4, the desired product, N-(1,1-dimethyl-3-piperidinobutyl)-3-methoxypropionamide, is obtained boiling at 112°-115° C./0.25 mm.
