실험 절차
To a solution of diethylamine (35 g, 0.48 mol) in benzene (75 ml), diketene (40.2 g, 0.48 mol) in benzene (100 ml) was added dropwise at 20°~30° C., stirring was continued for 1 hr. under reflux, and evaporated. The residue (75 g) was chromatographed on silica gel (wako Gel C-200) with dichloromethane/ethyl acetate (10:1) as eluent to give the title compound as a yellow viscous oil; yield: 48.4 g.
