실험 절차

A solution of 3-acetylbenzyl bromide (4 g) and ethyl acetoacetate sodium salt (3.42 g) in tetrahydrofuran (50 mL) was stirred for 12 hr. The insoluble material was filtered off and the filtrate was concentrated. The residue was purified by silica gel column chromatography to give the title compound (2.42 g, 49%) as a colorless viscous oil.
