실험 절차

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 rt for 30 min, 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 sat'd 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.
