Reaction Steps

A slurry of LiAlH4 (775 mg, 20.4 mmol) in dry Et2O (70 ml) at 0° C. was treated with a solution of 4-(4-fluorophenyl)-2-(1-methylethyl)-6-phenyl-3-pyridinecarboxylic acid, ethyl ester (4.80 gm, 13.2 mmol) in Et2O (5 ml). After 2.5 hours, the reaction was quenched and diluted with H2O and the aqueous layer was extracted twice with Et2O and once with EtOAc. The combined organic layers were washed with H2O and brine, then dried (Na2SO4), filtered and stripped. The resulting solid was dissolved in hot EtOAc and directly chromatographed (flash, Merck SiO2, 20% EtOAc in hexane) to give crude 4-(4-fluorophenyl)-2-(1-methylethyl)-6-phenyl-3-pyridinemethanol. Recrystallization from hot hexane/EtOAc gave 4-(4-fluorophenyl)-2-(1-methylethyl)-6-phenyl-3-pyridinemethanol (3.30 gm) as a white solid. The mother liquor was stripped and recrystallized again to give an additional 230 mg of product (total 3.53 gm, 84%).
