실험 절차

To a solution of 50 mg (0.14 mmol) of mitomycin A in 10 ml of anhydrous methanol was stirred with 150 mg (2 mmol) of N-methylpropargylamine at room temperature. The reaction appeared to be complete in 3 hours, as revealed by TLC. The solvent was removed by evaporation under reduced pressure and the residue was chromatographed using silica-gel as adsorbent. The fraction obtained by eluting the column with ethyl acetate was evaporated under reduced pressure. Recrystallization from a mixture of methylene chloride and hexane gave 20 mg (37% yield) of the desired product as purple-colored crystals having a melting point of 86°-87° C. (decomposing) and providing the following analysis:
