To a solution of (1S,4S)-5-allyloxycarbonyl-2 -thia-5-azabicyclo[2.2.1]heptan-3-one (39.2 mg) in acetonitrile (1 ml) were added dimethylamine hydrochloride (16.5 mg) and diisopropylethylamine (35.7 mg). The mixture was stirred for 3 hours at room temperature. After the reaction was over, 1N-hydrochloric acid (0.092 ml) was added thereto, and the mixture was diluted with ethyl acetate (2 ml) and dried over magnesium sulfate. Distillation of the solent, followed by purifying the residue by silica gel chromatography, gave oily (2S,4S) -N,N-dimethyl-1-allyloxycarbonyl-4-mercapto-2-pyrrolidinecarboxamide.
