Versuchsvorschrift

A preformed solution of 4-[2-(N-benzyl-N-(2-hydroxy-2-phenylethyl)amino)ethoxy]phenylacetamide in propan-2-ol and glacial acetic acid (see below) was hydrogenated in the presence of 10% w/w palladium on carbon (1.0 g) at about 20 bar and 60° C. for 12 hours. The mixture was cooled, filtered and the liltrate was evaporated under reduced pressure. The residual oil thus obtained was dissolved in ethyl acetate and treated with a solution of ether saturated with hydrogen chloride. The precipitated solid was crystallized from methanol to give 4-[2-(2-hydroxy-2-phenylethylamino)ethoxy]phenylacetamide hydrochloride (6.8 g), m.p. 250°-251° C. (softens at about 248° C.); microanalysis: found C, 61.2; H, 6.5; N, 8.3; Cl, 10.3%; required for C18H23ClN2O3 : C, 61.6; H, 61.6; N, 8.0; Cl, 10.1%.
