실험 절차

500 mg (1.388 mmol) of Example 4 were initially charged in acetone (50 ml), 0.274 ml (2.775 mmol) of piperidine was added and the mixture was heated under reflux for 1 h. After cooling, a precipitate was filtered off and washed with acetone, and the filtrate was concentrated under reduced pressure. This residue was then purified by chromatography on silica gel (mobile phase: cyclohexane/ethyl acetate gradient). The material obtained in this manner was once more slurried in ethyl acetate, filtered off, washed with ethyl acetate and dried under high vacuum. This gave 101 mg of the title compound as a solid (18% of theory).
