Procedure

5-[5-(4-Chloro-phenyl)-6-(2,2,2-trifluoro-ethoxy)-pyridin-3-ylcarbamoyl]-nicotinic acid ethyl ester (510 mg, 1.06 mmol) was combined with THF (25 mL), methanol (5 mL) and water (5 mL) to give a light yellow suspension. The reaction mixture was stirred for 4 h, and concentrated in vacuo. The reaction mixture was poured into 100 mL ethyl acetate and extracted with 1 M HCl (1×25 mL) and brine (1×25 mL). The aqueous layer phases were extracted with ethyl acetate (1×50 mL). The organic layers were combined, dried with Na2SO4 and concentrated in vacuo. The crude material was purified by flash chromatography (silica gel, 40 g, 0% to 100% ethyl acetate in heptane) to deliver 0.17 g (48.7%) of the title compound as white solid; MS (ESI) 450.0(M−H)−.
