275 gm of benzenesulfonic acid chloride were added to 4 gm of 3-[N-methyl-N-(2-{3,4-dimethoxy-phenyl}-ethyl)amino]-propanol. After standing for 30 minutes, the mixture was dissolved in methylene chloride, washed with an aqueous 30% sodium hydroxide solution and water, dried over sodium sulfate and evaporated in vacuo. After purifying the residue on a silica gel column (eluant: methylene chloride/ethanol) a colorless oil was obtained.
