4-(3-chloro-4-methoxybenzyloxy)-2-(methylmercapto)pyrimidine-5-carboxylic acid (300 mg, 0.88 mmol) and 4-fluorobenzylamine (165 mg, 1.32 mmol) were dissolved in 20 mL THF, DIEA (0.45 mL, 2.64 mmol) was added dropwise, HATU (401 mg, 1.06 mmol) was added under ice-water-bath, reacted at room temperature for 4 h, to the reaction solution was added 100 mL of water, then extracted with dichloromethane, dried with anhydrous sodium sulfate, dried by rotation, the solid was separated with silica gel separation (dichloromethane:methanol=100:1) to obtain a white solid 4-(3-chloro-4-methoxybenzyloxy)-2-(methylmercapto)-N-(4-fluorobenzyl)pyrimidine-5-carboxamide 206 mg, yield 52%.
