Methanol → 1,1a,2,8,8a,8b-Hexahydro-8-(hydroxymethyl)-8a-methoxy-5-methyl-6-furfurylamino-azirino[2',3':3,4]pyrrolo-[1,2-a]indole-4,7-dione carbamate

反応手順

To a solution of 60 mg (0.17 mmol) of mitomycin A in 8 ml of anhydrous methanol, 0.5 ml of furfurylamine was added with stirring. The progress of the reaction was periodically checked by TLC and the reaction appeared to be complete in 3 hours. 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. Recrystallization from a mixture of chloroform and hexane gave 30 mg (42.7% yield) of the desired product as purple-colored crystals having a melting point of 62°-63° (decomposing) and providing the following analysis:
