Procedure
The mixture of N-phenylglycine methyl ester (0.99 g, 6 mmol), potassium carbonate (1.66 g, 12 mmol), and iodomethane (1.28 g, 9 mmol) in acetonitrile (20 mL) was refluxed overnight. The solids were filtered and the filtrate was diluted with water (100 mL), extracted with dichloromethane (4×50 mL). The combined organic extracts were washed with brine (100 mL), dried (Na2SO4), filtered, and concentrated under reduced pressure. The crude product was purified by flash chromatography (silica gel, ethyl acetate/hexane) to afford the title compound (0.82 g, 77%). 1H NMR (400 MHz, CDCl3) δ: 7.24 (m, 2H), 6.75 (m, 1H), 6.67 (m, 2H), 4.07 (s, 2H), 3.71 (s, 3H), 3.06 (s, 3H).
