실험 절차
Introduce into a reactor 200 g of N-[(S)-ethoxycarbonyl-1-butyl]-(S)-alanine and 1.5 liters of dichloromethane and then, at 0° C., add 325 g of 1H-imidazole-1-sulphinyl chloride. Subsequently, bring the reaction mixture to ambient temperature and then, after stirring for 1 hour, filter off the precipitate formed. The filtrate obtained is evaporated to dryness to yield the expected product in the form of an oil.
