Procedure

A mixture of 400 mg of (R)-4-hexadecyl-4-[(phenylmethoxy)methyl]-2-azetidinone, 50 mg of 10% palladium-on-carbon and 20 ml of methanol:acetic acid (1:1) is hydrogenated for 16 hours, then filtered and evaporated. The residue is recrystallized from petroleum ether/ethyl acetate, to give 300 mg of the desired compound as a white solid, mp. 82° C.
