A mixture of (7-(4-amino-2-fluorophenoxy)thieno[3,2-b]pyridin-2-yl)(3-(tert-butyldimethylsilyloxy)azetidin-1-yl)methanone 274 (145.2 mg, 0.31 mmol), 27 (77 mg, 0.367 mmol), and EDC (70.3 mg, 0.367 mmol) in DMF (4.4 mL) was stirred overnight at room temperature. The crude mixture was diluted with EtOAc, extracted with water, dried over anhydrous Na2SO4 and concentrated under reduced pressure affording crude 275 (178.4 mg, 0.269 mmol, 87% yield) that was used in the next step without further purification. MS (m/z): (M+1) 665.1 (100%).
