실험 절차

To a solution of the above-mentioned crude product of methyl 3-(2-cyanoethenyl)benzoate in ethanol (45 mL)/tetrahydrofuran (15 mL) was added 10% palladium-carbon (648 mg), and the mixture was stirred at room temperature under a hydrogen atmosphere (1 atm) for 2 hr. The insoluble material was filtered off, and the filtrate was concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane/ethyl acetate=90/10→75/25), and the fractions containing the object product were concentrated under reduced pressure to give the title compound (2.03 g, 88%) as a colorless oil.
