실험 절차

A solution of (3S,4S)-4-(1-hydroxy-1-methylethyl)-3-(1-(R)-benzyloxycarbonyloxyethyl)-1-di(p-anisyl)methyl-2-azetidinone (30 g) in dry toluene (350 ml) was treated with thionyl chloride (9.0 g) at 20°-30° C. for 5 hours in the presence of pyridine (10 ml). Water (100 ml) was added to quench the reaction at 10°-25° C. The organic layer was separated, washed with water and dried over anhydrous sodium sulfate. After filtration, the filtrate was concentrated in vacuo to give an oily residue, which was crystallized from a mixture of cyclohexane and ethyl acetate yield (3S,4S)-4-(1-methylethenyl)-3-(1-(R)-benzyloxycarbonyloxyethyl)-1-di(p-anisyl)methyl-2-azetidinone. m.p., 117°-118° C.
