Reaction Steps
To a solution of ethyl imidocarbamate tetrafluoroborate (2.4 g) and ethyl 2-benzyl-3-oxobutanoate (1 g) in methanol (20 mL) was added sodium methoxide (28% methanol solution, 5.25 mL), and the mixture was stirred for 12 hr. The reaction mixture was concentrated, and the residue was dissolved in water. The solution was weakly acidified with acetic acid, extracted with ethyl acetate, washed with saturated brine and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. The residue was crystallized from diisopropyl ether to give the title compound (0.27 g, 24%) as a colorless solid.
