Reaction Steps

2.9 grams of 5-(piperazinylpropoxy)-3,4-dihydrocarbostyril, 2.5 g of o-bromoethoxybenzene and 1.5 g of sodium carbonate are mixed with 80 ml of n-butanol and refluxed for 20 hours. After cooling, the reaction mixture is concentrated under reduced pressure and the residue is extracted with chloroform. Then chloroform is removed by distillation and the residue thus obtained is recrystallized from ethanol to obtain 2.2 g of 5-{3-[4-(2-ethoxyphenyl)piperazinyl]propoxy}-3,4-dihydrocarbostyril in the form of colorless needle-like crystals having a melting point of 155°-156° C.
