実験手順

Pulverized potassium carbonate (0.76 g, 5.5 mmole) and potassium iodide (0.97 g, 5.5 mmole) was added to a mixture of 4-(5-fluoro-1H-indol-3-ylmethyl)piperidine (1.16 g, 5.0 mmole) and 1-(2-chloroethyl)-4-(2-methoxyphenyl)piperazine (1.27 g, 5.0 mmole) in 25 ml of acetonitrile. The resulting mixture was heated to reflux under nitrogen for 5 hours. After cooling, it was diluted with water (150 ml) and the product extracted into ethyl acetate (50 ml). The organic layer was washed with water (50 ml), brine (50 ml), and after drying over sodium sulfate, filtration and concentration in vacuo afforded the required product as a white solid (1.8 g, 80%). Treatment with an excess of 1M etheral hydrochloric acid gave the acid addition salt, which was recrystallized from methanol.
