Reaction Steps

A 3.0 ml portion of ethylenediamine was added to a mixture of 1.0 g of 2-(benzotriazol-1-yloxy)-4-(4-methylanilino)pyrimidine-5-carboxamide and 30 ml of acetonitrile, followed by stirring at room temperature for 1 hour and 40 minutes. Water was added to the reaction mixture, followed by extraction with a chloroform-isopropanol mixed solution. The resulting organic layer was dried over anhydrous sodium sulfate and concentrated under a reduced pressure and then the thus obtained residue was purified by silica gel column chromatography (eluting solvent; chloroform:methanol:aqueous ammonia) . By recrystallizing the thus obtained colorless solid from an ethyl acetate-ethanol mixed solvent, 471 mg of 2-(2-aminoethylamino)-4-(4-methylanilino)pyrimidine-5-carboxamide was obtained (colorless crystals).
