Reaction Steps

To a solution of 7-[4-(4-benzo[b]thiophen-4-yl-piperazin-1-yl)-butoxy]-1H-quinolin-2-one (800 mg) synthesized in the same manner as in WO2006/112464 (Example 1) in dichloromethane (20 ml) was added triethylamine (0.65 ml), with stirring under ice-cooling, diethylcarbamoylchloride (0.5 g) was added and the mixture was stirred at room temperature overnight. Water, was added to the reaction mixture and the mixture was extracted with ethyl acetate. The organic layer was dried over sodium sulfate. The solvent was evaporated under reduced pressure and the residue was purified by silica gel column chromatography (ethyl acetate:n-hexane=20:1) to give 7-[4-(4-benzo[b]thiophen-4-yl-piperazin-1-yl)-butoxy]-quinolin-2-yl diethylcarbamate (120 mg).
