実験手順

A solution of 30 g of crude 1-[N-[2-(3-carbamoyl-4-hydroxyphenoxy)-ethyl]-benzylamino]-3-[4-[2-(cyclopropylmethoxy)ethyl]-phenoxy]-2-propanol in 600 ml of methanol is hydrogenated, with the addition of 4 g of a Pd/C catalyst (5%), under normal conditions until 1 mol-equivalent of hydrogen has been absorbed. By the addition of dioxane and by heating, the product which has already crystallied out is taken into solution; the catalyst is filtered off and the filtrate is concentrated by evaporation. Recrystallisation from isopropanol and then from methanol yields pure 1-[2-(3-carbamoyl-4-hydroxy-phenoxy)-ethylamino]-3-[4-[2-(cyclopropylmethoxy)-ethyl]-phenoxy]-2-propanol, m.p. 149°-150°.
