Reaction Steps

A stirred solution of 2-fluoro-3-hydroxybenzonitrile (800 mg, 5.83 mmol) in DMF (10 mL) at 0° C. was treated portionwise with NaH (280 mg, 7.00 mmol) (60% oil dispersion). The reaction mixture was then stirred for 0.5 h and 2,2,2-trifluoroethyl trifluoromethanesulfonate (1490 mg, 6.42 mmol) was added. The reaction was allowed to warm to rt overnight with stirring. The reaction mixture was then treated with water (40 mL) and brine (5 mL) and extracted with ethyl acetate (˜50 mL). The organic extract was washed with water, dried over anhydrous Na2SO4, filtered and conc. in vacuo to afford a residue which was purified via silica gel chromatography (10% to 30% ethyl acetate/hexanes) to yield the title compound as a white solid (1040 mg, 81%). 1H NMR (400 MHz, MeOD) δ ppm 7.56 (td, 1 H), 7.47-7.38 (m, 1 H), 7.38-7.24 (m, 1 H), 4.73 (q, 2 H); m/z 220.
