To a solution of 4-(2-chlorothieno[2,3-d]pyrimidin-4-yloxy)-3,5-dimethylbenzonitrile (188 mg, 0.59 mmol), TFA (0.37 mL, 4.75 mmol) in TFE (2.5 mL) was added 4-aminobenzonitrile (280 mg, 2.37 mmol) in a sealed tube. The reaction was stirred at 90° C. for 2 d. 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 HPLC afforded the product as white solid (34 mg, 14%):
