実験手順

A mixture of 9.0 g of 7-(4-chlorobutoxy)-1H-quinolin-2-one, 10 g of 1-benzo[b]thiophene-4-yl-piperazine hydrochloride, 14 g of potassium carbonate, 6 g of sodium iodide and 90 ml of dimethylformamide was stirred for 2 hours at 80° C. Water was added to the reaction solution and precipitated crystals were separated by filtration. The crystals were dissolved in a mixed solvent of dichloromethane and methanol, dried over magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (dichloromethane:methanol=100:3). Recrystallized from ethanol, 13.6 g of 7-[4-(4-benzo[b]thiophen-4-yl-piperazin-1-yl)butoxy]-1H-quinolin-2-one in the form of a white powder was obtained.
