실험 절차

N-Allyl-N-p-tolyl-hydrazine (600 mg, 3.70 mmol) and 3-[2-(4-fluoro-phenyl)-allyl]-1,3-dimethyl-piperidin-4-one (970 mg, 3.71 mmol) were dissolved in 1,4-dioxane (4 mL). Trifluoroacetic acid (1 mL) was added and the reaction mixture was heated to 100° C. for 3 h. 1,4-Dioxane was removed under reduced pressure, the residue was basified with aqueous sodium bicarbonate, and extracted with EtOAc (2×30 mL). The organic layer was dried over sodium sulfate and concentrated under reduced pressure. The residue was purified by column chromatography over silica gel (100-200 mesh, eluent as 5% EtOAc in hexane) to obtain 290 mg of 5-allyl-4-[2-(4-fluoro-phenyl)-allyl]-2,4,8-trimethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole.
