Procedure

Purge a mixture of methyl 5-cyano-2-(difluoromethyl)benzoate (9.37 g, 44.4 mmol, 1.0 equiv), palladium (10% on carbon, 3.00 g, 2.82 mmol, 0.064 equiv), and MeOH (50 mL) with nitrogen; then add hydrochloric acid (37 wt % aqueous, 8.0 mL, 105.6 mmol, 2.38 equiv); and stir the resulting suspension under 275 kPag of hydrogen at room temperature overnight. Remove the solids by filtration; concentrate the filtrate under reduced pressure; and dry the resulting material in a 40° C. vacuum oven overnight to give the title compound as a light brown solid (7.01 g, 83% yield). ES/MS (m/z) 216 (M+1).
