실험 절차

A solution of (3R,4R)-4-(2,2-dimethoxyethyl)-3-phthalimido-2-oxoazetidine (65 mg) in 80% aqueous acetic acid (1.5 ml) was heated at 64° for two hours. After evaporation of the solvent in vacuo, the residue was crystallized from a mixture of diethyl ether and ethyl acetate to afford (3R,4R)-4-(2-oxoethyl)-3-phthalimido-2-oxoazetidine (42 mg).
