Sodium hydride → Methyl 2-[(2'-cyano-3,5-difluorobiphenyl-4-yl)methyl]-3-oxoheptanoate

Participants

Reaction Steps

To a solution of methyl 3-oxoheptanoate (6.82 g) in tetrahydrofuran (75 mL) was added 60% sodium hydride (1.29 g), and the mixture was stirred for 1 hr. A solution of 4′-(bromomethyl)-3′,5′-difluorobiphenyl-2-carbonitrile (6.65 g) in tetrahydrofuran (25 mL), and the mixture was stirred for 15 hr. Ammonium chloride and water were added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate, and the solvent was evaporated. The residue was purified by silica gel column chromatography to give the title compound as a pale-yellow viscous substance (7.93 g, 100%).
