Versuchsvorschrift

0.1 g of sodium hydride (60% oil dispersion) is added to a solution of one g of N-methyl-2-{2-[2-(4-(3-fluorophenyl)piperazin-1-yl)ethyloxy]phenyl}thiazolidine-3-carboxamide in 30 ml of dimethylformamide, and a solution of 0.19 g of acetyl chloride in 5 ml of ether is added thereto. After the mixture is stirred at 50° C. for 20 hours, the mixture is concentrated under reduced pressure to remove solvent. Water is added to the residue, and the aqueous mixture is extracted with ethyl acetate. The extract is washed with water, dried and then concentrated under reduced pressure to remove solvent. The residue is purified by silica gel chromatography (solvent, ethyl acetate:n-hexane=4:1). 0.32 g of N-acetyl-N-methyl-2-{2-[2-(4-(3-fluorophenyl)piperazin-1-yl)ethyloxy]phenyl}thiazolidine-3-carboxamide is obtained as an oil.
