実験手順

A mixture of 1.12 g of potassium isocyanate, 10 ml of water and 2 ml of acetic acid is added to a solution of 2.68 g of 2-{2-[2-(4-(3-fluorophenyl)piperazin-1-yl)ethyloxy]phenyl}thiazolidine in 20 ml of ethanol, and the mixture is stirred at room temperature for 2 hours. A mixture of 0.56 g of potassium isocyanate and 0.5 ml of acetic acid is added to said mixture, and the mixture is stirred at the same temperature for 2 hours. The mixture is made alkaline with sodium bicarbonate and concentrated under reduced pressure to remove solvent. The residue is extracted with ethyl acetate. The extract is washed with a saturated sodium chloride solution, dried and then concentrated under reduced pressure to remove solvent. The residue is purified by silica gel chromatograph (solvent, ethyl acetate), and the resultant product is recrystallized from a mixture of ethyl acetate and ether. 2.6 g of 2-{2-[2-(4-(3-fluorophenyl)piperazin-1-yl)ethyloxy]phenyl}thiazolidine-3-carboxamide are obtained.
