Reaction Steps
A solution of 3.8 g of 3-[4-(2-methoxyphenyl)-piperazin-1-yl]-1-hydroxy-propane in 40 ml of acetone is added dropwise at 20° C to a stirred solution of 4.9 g of xanthene-9-carbonyl chloride in 30 ml of acetone. The reaction mixture is refluxed for 30 minutes, allowed to cool to 60° C, and then ethanolic hydrochloric acid is added to the mixture until no more crystalline substance separates. The reaction mixture is cooled to 0° C, the separated crude substance is filtered off, and the crude substance is recrystallized from 20 ml of a 1:2 mixture of water and ethanol. 5.3 g (73%) of 3-[4-(2-methoxyphenyl)-piperazin-1-yl]-1-(xanthene-9-carbonyloxy)-propane hydrochloride are obtained; m.p.: 193°-195° C.
