실험 절차

4-Fluoro-N-methylaniline (0.33 g, 2.67 mmol) is added to a solution of ethyl 2-bromo-2-phenylacetate (0.36 mL, 2.06 mmol) in acetonitrile (6.86 mL) and DIPEA (0.47 ml, 2.67 mmol). The dark solution is stirred at 100° C. under microwave irradiation for 1 hour. Then solvent is evaporated and the crude is purified by flash chromatography (Petroleum ether/EtOAc=97/3) to obtain intermediate I118 as a yellow solid (0.59 g, 100% yield).
