Procedure

To a mixture of 4-(3-chloro-4-methoxybenzylamino)-5-carboxy-6-methoxy-2-methylthiopyrimidine (prepared in the above (2)) 183 mg, 2-aminomethylpyrimidine 70 mg, 1-hydroxybenzotriazole hydrate 67 mg and dimethylformamide 4 ml is added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimido hydrochloride 114 mg on an ice bath, and the mixture is stirred for 14 hours at room temperature. The reaction mixture is diluted with an aqueous sodium hydrogen carbonate solution and extracted with ethyl acetate. The ethyl acetate layer is washed, dried and concentrated in vacuo. The residue is separated with silica gel chromatography (solvent; chloroform:ethyl acetate=20:1→10:1) to give 4-(3-chloro-4-methoxybenzylamino)-5-[N-(2-pyrimidinylmethyl)carbamoyl]-6-methoxy-2-methylthiopyrimidine as a colorless crystalline powder 208 mg. mp 171-172° C.
