실험 절차
N-Benzylazetidine-2-carboxylic acid methyl ester (1.4 g) was dissolved in 40 ml of t-butyl methyl ether at 20 to 25° C. and stirred for one minute and 70 mg of Enzyme (Chirazyme L-2) suspended in 2 ml of water was poured thereto and the resulting solution was heated to 40° C. and stirred for 14 hours. Settled solution was separated into an aqueous phase and an organic phase. The aqueous phase was washed twice with t-butyl methyl ether (5 ml) to yield an aqueous solution of optically active N-benzylazetidine-2-carboxylic acid and a combined organic phase of N-Benzylazetidine-2-carboxylic acid methyl ester.
