Reaction Steps

2,5-Difluoroaniline (0.19 mL, 1.85 mmol), ethyl 2-bromo-2-phenylacetate (0.22 mL, 1.23 mmol), and DIPEA (0.32 mL, 1.85 mmol) are dissolved in acetonitrile (3 mL) and heated under MW irradiation at 100° C. for 6 hours and then at 110° C. for 4 hours. Acetonitrile is evaporated and the crude is purified by flash chromatography (Petroleum ether/EtOAc=97/3) to obtain intermediate I104 as a white solid (240 mg, 67% yield).
