Reaction Steps

To a solution of 2-Chloro-N-mesitylthieno[3,2-d]pyrimidin-4-amine (51.4mg, 0.17 mmol), TFA (0.11 mL, 1.36 mmol) in TFE (1 mL) was added 4-aminobenzonitrile (80.2 mg, 0.68 mmol) in a sealed tube. The reaction was stirred at 90° C. for 15 h. Reaction mixture was diluted with ethyl acetate 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 to afford the product as a white solid (13 mg, 20%):
