実験手順

4-((1,5-dimethyl-1H-1,2,4-triazol-3-yl)amino)-2-(methylthio)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (157 mg, 0.521 mmol) was taken up in DMF (6 mL) under argon and NaH (22.92 mg, 0.573 mmol) was added. The reaction mixture was stirred at room temperature for 30 min, and then alpha-chloro-4-methoxytoluene (0.074 mL, 0.547 mmol) was added. The reaction mixture was heated at 80° C. for 3 h. The reaction was quenched with saturated NaHCO3 solution and extracted 3× with EtOAc. The organic layers were combined, dried over Na2SO4, filtered, and concentrated to give 4-((1,5-dimethyl-1H-1,2,4-triazol-3-yl)(4-methoxybenzyl)amino)-2-(methylthio)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (185 mg) as a red solid.
