Reaction Steps

To a solution of 2,4-dichlorothieno[3,2-d]pyrimidine (148 mg, 0.73 mmol), TFA (0.17 mL, 2.19 mmol) in TFE (2 mL) was added 2,4,6-trimethylaniline (0.15 mg, 1.1 mmol) in a sealed tube. The reaction was stirred at 90° C. for 15 h. The reaction mixture was diluted with CH2Cl2 and washed with saturated NaHCO3 solution (3×20 mL). The combined organic layers were washed with brine, dried over Na2SO4, filtered, and concentrated in vacuo. The crude product was purified by column chromatography eluting with Hexanes:ethyl acetate (4:1) to afford the product as a white solid (51.4 mg, 23%):
