Participants

Reaction Steps

To a solution of 2-(2-pyridylmethoxy)-5-(3,4,5-trimethoxyphenyl-carbonyl)-4-(3-metylamino-4-methoxybenzylamino)pyrimidine (prepared in Example 48) 42 mg in methylene chloride 3 ml are added mesyl chloride 48 mg and triethylamine 69 mg, for three times at one hour intervals. The reaction mixture is stirred for 1 hour at room temperature. Ethyl acetate and an aqueous saturated sodium hydrogen carbonate solution is added thereto. The organic layer is separated, washed with brine and dried over anhydrous sodium sulfate. After filtration of sodium sulfate the filtrate is concentrated in vacuo and the residue is purified by preparative thin-layer chromatograph (2 plates, solvent:ethyl acetate) to give 2-(2-pyridylmethoxy)-5-(3,4,5-trimethoxyphenylcarbonyl)-4-[4-methoxy-3-(N-methylmethansulfonylamino)benzylamino]pyrimidine as a colorless amorphous 20 mg.
