Procedure

A mixture of 2-chloro-4-(3-chloro-4-methoxybenzylamino)-5-(2-pyridylcarbonyl)pyrimidine (prepared in Example 90-(3)) 110 mg, 2-pyridinemethanol 34 mg, 10% sodium hydride 12 mg and tetrahydrofuran 3 ml is stirred at room temperature for 5 minutes. The reaction mixture is poured into water and extracted with ethyl acetate. The organic layer is washed with brine, dried over anhydrous sodium sulfate and concentrated in vacuo. The residue is purified by silica gel chromatography (solvent: ethyl acetate) and triturated with ethyl ether to give 2-(2-pyridylmethoxy)-4-(3-chloro-4-methoxybenzylamino)-5-(2-pyridylcarbonyl)pyrimidine, 104 mg. mp 81–84° C., MS(m/z): 462(M+H)+
