1.8 g (0.01 mol) of proline ethyl ester hydrochloride and 1.0 g of triethylamine were added dropwise to 30 ml of benzene and 2.6 g (0.01 mol) of 4-chloro-3-isopropoxycarbonylphenyl isothiocyanate were added thereto. The mixture was stirred at room temperature for an hour, washed with water, dried over anhydrous sodium sulfate, and then concentrated.
