Reaction Steps

To a solution of 4-(2-chlorothieno[3,2-d]pyrimidin-4-yloxy)-3,5-dimethylbenzonitrile (187 mg, 0.6 mmol), TFA (0.37 mL, 4.8 mmol) in TFE (3 mL) was added 4-aminobenzonitrile (283 mg, 2.4 mmol) in a sealed tube. The reaction was stirred at 90° C. for 15 h. Reaction mixture was diluted with ethyl acetate (5 mL) and washed with saturated NaHCO3 (3×10 mL). The combined organic layers were washed with brine, dried over Na2SO4, filtered and concentrated in vacuo. The crude product was purified by prep HPLC afforded the product as a white solid (81 mg, 34%):
