Procedure

To a solution of 115 mg mitomycin A (0.33 mmol) in 5 ml of anhydrous methanol, 71 mg 3-aminomethylpyridine (0.66 mmol) was added and the mixture was stirred. The progress of the reaction was checked by TLC and appeared to be complete in 16 hours. The solvent was removed by evaporation under reduced pressure. The residue was chromatographed using silica-gel as adsorbent. The fraction obtained by eluting the column with a mixture of chloroform and ethyl acetate (1:1 by volume) was evaporated to give 107 mg (76% yield) of the desired product as purple-colored crystals having a melting point of 116°-118° C. after recrystallization from chloroform-hexane and providing the following analysis:
