Reaction Steps

To a solution of ethyl 3-oxo-2-phenylbutanoate (2.28 g) and butanimidamide hydrochloride (2.04 g) in N,N-dimethylformamide (30 mL) was added 1,8-diazabicyclo[5.4.0]undec-7-ene (5.0 mL), and the mixture was stirred at 100° C. for 15 hr. Ethyl acetate and water were added to the reaction mixture, and the aqueous layer was extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate. The solvent was evaporated and the residue was purified by silica gel column chromatography to give the title compound as a pale-yellow viscous substance (0.26 g, 10%).
