Reaction Conditions

Reaction Steps

A mixture of 2.38 g of N-methyl-2-(2-hydroxyphenyl)thiazolidine-3-carboxamide, 1.38 g of potassium carbonate, 0.7 g of sodium iodide, 3.36 g of 1-(2-chloroethyl)-4-phenylpiperazine and 25 ml of dimethylformamide is stirred at 90° C. for 24 hours. The mixture is concentrated under reduced pressure to remove dimethylformamide. Water is added to the residue, and the aqueous mixture is extacted with ethyl acetate. The extract is washed with dilute sodium hydroxide solution and water, successively. The ethyl acetate solution is dried and then concentrated under reduced pressure to remove solvent. The residue is purified by silica gel chromatography (sovent, benzene:ethyl acetate-1:5). 1.89 g of N-methyl-2-{2-[2-(4-phenylpiperazin-1-yl)ethyloxy]phenyl}thiazolidine-3-carboxamide are obtained.
