1-(2-Aminophenyl)ethanone (250 mg, 1.85 mmol), ethyl 2-bromo-2-phenylacetate (0.22 ml, 1.23 mmol), DIPEA (0.32 mL, 1.85 mmol) and a catalytic amount of potassium iodide are dissolved in acetonitrile (4 mL) and heated under MW irradiation at 100° C. for 2 hours and then at 120° C. for 1 hour. Acetonitrile is evaporated and the crude is purified by flash chromatography (petroleum ether/EtOAc=93/7) to obtain intermediate I110 as a yellow oil (367 mg, quantitative yield).
