実験手順
To a solution of (1R)-2-(1H-indol-3-yl)-1-(4-phenyl-1H-imidazol-2-yl)-1-ethanamine hydrochloride (1 g, 2.65 mmol) in isopropanol (15 ml) was added N-benzoyl-4-piperidone (2.64 g, 13 mmol). The solution was refluxed for about one hour and cooled to about 20° C. The solvent was removed under reduced pressure. The residue was treated with dichloromethane (30 ml) and stirred for about 30 min at about 20° C. The resulting precipitate was collected by filtration, washed with dichloromethane and diethyl ether, and dried to afford 1.2 g of the title product as the hydrochloride salt. Melting point: 240-244° C.
