실험 절차

The procedure is as in Example 25, starting with (RS)-2-(2-bromoethyl)-3-methoxyisoindolinone (2.4 g), 4-[(5-fluoro-3-indolyl)methyl]piperidine (2.1 g) and sodium bicarbonate (0.74 g) in a mixture of dimethylformamide (50 cc) and tetrahydrofuran (40 cc). The mixture is heated to boiling for 10 hours and then cooled to a temperature in the region of 20° C. After purification by flash chromatography on a silica column under a stream of nitrogen at moderate pressure (0.5-1.5 bar) with ethyl acetate as eluent, and recrystallization a first time in acetonitrile (40 cc) and then in methyl ethyl ketone (35 cc), (RS)-2-{2-[4-((5-fluoro-3-indolyl)methyl)piperidino]ethyl}-3-methoxyisoindolinone (0.8 g), m.p. 175° C., is obtained.
