Reaction Steps

To a solution of (4-ethoxy-2,6-difluoro-phenyl)-hydroxy-acetic acid ethyl ester (4.0 g, 15.37 mmol, 1.0 equiv) in toluene (50 mL) was added iodo-methane (21.82 g, 9.78 mL, 153.70 mmol, 10.0 equiv) and silver(I) oxide (7.12 g, 30.74 mmol, 2.0 equiv) and the reaction mixture heated to 60° C. for 18 h. The reaction mixture was filtered, the filtrate poured into ice water and then extracted with ethyl acetate. The organic layer was washed with water, dried over Na2SO4 and concentrated by evaporation under reduced pressure yielding 4.1 g (97%) of the title compound. 1H NMR (300 MHz, CDCl3): 1.25 (t, J=7.5 Hz, 3H), 1.41 (t, J=7.5 Hz, 3H), 3.43 (s, 3H), 4.01 (q, J=7.5 Hz, 2H), 4.26 (q, J=7.5 Hz, 2H), 5.05 (s, 1H), 6.43-6.48 (m, 2H). MS (ISP): 292.3 [M+NH4]+.
