実験手順
To (4S)-4-mercapto-L-proline hydrochloride (300 mg) is added 2 N sodium hydroxide (1.6 ml) aqueous solution, and the mixture is stirred at 0° C. A solution of 4-cyclohexylbenzyl chloride (340 mg) in a mixed solvent of ethanol (5 ml)/chloroform (1 ml) is added thereto, and the mixture is stirred at room temperature overnight. The reaction mixture is concentrated under reduced pressure, and deposited crystals are filtered off. The crystals are washed with water, ethanol and diethyl ether successively to give 470 mg (91%) of the titled compound.
