Versuchsvorschrift
A solution of 3.5 g of 1-[3-(2-methoxyphenoxy)-2-hydroxypropyl]-4-[(2,6-dimethylphenyl)aminocarbonylmethyl]piperazine dihydrochloride salt in water (50 ml) is adjusted to pH 12 with ammonium hydroxide solution and extracted with methylene chloride. The methylene chloride is evaporated to afford 3 g of 1-[3-(2-methoxyphenoxy)-2-hydroxypropyl]-4-[(2,6-dimethylphenyl)aminocarbonylmethyl]piperazine as the free base.
