الإجراء التجريبي

To a solution of 4-(4-aminophenylamino)-6-(3,4-dimethoxyphenyl)-2-methylpyrimidine (1.0 g) in 1,2-dichloroethane (20 ml) were added methanesulfonyl chloride (0.28 ml) and triethylamine (0.83 ml) and the mixture was refluxed for 3 hours. After cooled, chloroform (50 ml) was added thereto, and washed with water. The solution was dried over magnesium sulfate, evaporated, and chromatographed on silica gel eluting with chloroform to give 6-(3,4-dimethoxyphenyl)-4-(4-mesylaminophenylamino)-2-methylpyrimidine (0.45 g).
