Reaction Steps

3-(2-Chlorothieno[3,2-d]pyrimidin-7-yl)benzenamine (800 mg, 3.06 mmol) was dissolved in anhydrous tetrahydrofuran (15 mL) and methanesulfonyl chloride (0.27 mL, 3.37 mmol) and triethylamine (0.85 mL, 6.13 mmol) were added. The mixture solution was stirred for 2 hours, diluted with ethyl acetate, and then washed with brine. The organic layer was concentrated by drying with magnesium sulfate. Purification by chromatography (10% ethyl acetate/hexane) yielded the target compound (950 mg, 91% yield).
