실험 절차
2-(S)-(3-dimethylaminomethylene-thioureidomethyl)-pyrrolidine-1-carboxylic acid 1,1-dimethylethyl ester was prepared from (S)-2-(aminomethyl)-1-pyrrolidinecarboxylic acid 1,1-dimethylethyl ester according to the procedure described in Example A (4-(3-dimethylaminomethylene -thioureidomethyl)-piperidine-1-carboxylic acid tert-butyl ester). Purified by column chromatography on silica gel (2:1 to 3:1 ethyl acetate/hexane eluant). Yellow solid. MS: 315.4 (M+H)+
