Participants

Reaction Steps

To a suspension of acetamidine hydrochloride (6.7 g) in methanol (50 mL) were added sodium methoxide (28% methanol solution, 20.5 mL) and then methyl 2-[(2′-cyano-3-fluorobiphenyl-4-yl)methyl]-3-oxoheptanoate (13.0 g), and the mixture was stirred for 15 hr. Water was 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 triturated with diisopropyl ether to give the title compound (9.15 g, 69%) as pale-yellow crystals.
