실험 절차

A solution of 16 g of crude 1-[N-[3-(3-carbamoyl-4-hydroxyphenyl)propyl]benzylamino]-3-[4-(2-methoxyethoxy)phenoxy]propan-2-ol is hydrogenated analogously to Example 1. The hydrogenating solution is neutralised with a solution of hydrochloric acid gas in methanol, concentrated by evaporation and crystallised from acetone. In this manner 1-[3-(3-carbamoyl-4-hydroxyphenyl)propylamino]-3-[4-(2-methoxyethoxy)phenoxy]propan-2-ol is obtained as a hydrochloride having a melting point of 194°-200°.
