Procedure

3-(3-Nitropyridin-4-yl)-5-(trifluoromethyl)cyclohex-2-enone (1.0 eq) was mixed with cerium(III) chloride heptahydrate (1.0 eq) and absolute ethanol (0.17) was added. The mixture was stirred at ambient temperature until all solids dissolved. the mixture was cooled on an ice bath and NaBH4 (1.2 eq) was added portion wise. The reaction was stirred on the ice bath for 1 h. The mixture was diluted with EtOAc, washed with water, dried over MgSO4, filtered and concentrated. The residue was purified by column (1:1 ethyl acetate and hexanes) to give cis-3-(3-nitropyridin-4-yl)-5-(trifluoromethyl)cyclohex-2-enol (66%). LC/MS (m/z): MH+=289.2, Rt=0.72 min.
