Versuchsvorschrift

A solution of 4-(2-acetoxyvinyl)-4-methyl-2-azetidinone (10.0 g) 200 ml ethyl acetate containing 100 mg of 10% Pd/C is hydrogenated on a Parr shaker at 25° C. under 40 psi hydrogen for 15 minutes. The mixture is filtered through a bed of Supercel and washed with additional ethyl acetate. The combined filtrate is evaporated in vacuo to give 4-(2-acetoxyethyl)-4-methyl-2-azetidinone.
