실험 절차
4 gm of 1-(4'-amino-3'-bromo-5'-cyano-phenyl)-2-cyclopropylamino-ethanol was dissolved in methanol, and the solution was hydrogenated at room temperature at a hydrogen pressure of 3 to 5 atmospheres after addition of 1 gm of palladized coal (10%). After termination of hydrogen absorption, the catalyst was suction-filtered off, the filtrate was evaporated to dryness in vacuo, and the residue was distributed between dilute sodium hydroxide and chloroform. After evaporation of the chloroform phase, 1-(4'-amino-3'-cyano-phenyl)-2-cyclopropylamino-ethanol was obtained as an oil, which was purified chromatographically on silicagel (eluant: chloroform:methanol = 9:1). The dihydrochloride, obtained by addition of ethereal hydrochloric acid, was recrystallized from isopropanol. M.p. 148°-151° C. (decomp.).
