In DMF (60 mL) were dissolved 4-((3-chloro-4-methoxybenzyl)amino)-2-(methylthio) pyrimidine-5-carboxylic acid (1.0 g, 2.95 mmol), pyrimidine 2-ylmethylamine (570 mg, 5.22 mmol) and HATU (2-(7-azabenzotriazole)-N,N,N′,N′-tetramethyluronium hexafluorophosphate, 2.64 g, 6.96 mmol), then DIEA (152 mg, 1.2 mmol) was added dropwisely. The reaction mixture was stirred at 60° C. overnight, extracted with DCM after water was added and washed with brine. The organic phase was dried over sodium sulfate. The solvent was removed by rotary evaporation, then the solid obtained was purified by silica gel column chromatography (DCM/methanol=50/1) to give 4-((3-chloro-4-methoxybenzyl)amino)-2-(methylthio)-N-(pyrimidin-2-ylmethyl)pyrimidine-5-formamide (350 mg, 13% yield).
