Reaction Steps

46 g of 1-(2-methoxyphenyl)-piperazine and 24.5 g of trimethylene chlorohydrine are dissolved in 200 ml of ethanol, and 25 g of potassium carbonate are added to the solution. The mixture is refluxed for 30 hours, thereafter it is cooled to 0° C., diluted with 50 ml of ethyl ether, filtered, and the filtrate is evaporated. The residue is dissolved in 100 ml of 50° C. benzene, the solution is cooled to 0° C., and allowed to stand for 10 hours. The separated crystals are filtered off and dried. 46 g (77%) of 3-[4-(2-methoxyphenyl)-piperazin-1-yl]-1-hydroxy-propane are obtained; m.p.: 92°-93° C.
