실험 절차

At a temperature of 65° C., sodium borohydride was added to a solution of 1-(2-amino-6-chloro-phenyl)-ethanone in ethanol, and the mixture was heated overnight (65° C.). Water, KSCN and HCl were then added subsequently, and the mixture was again heated (3 h, 65° C.). The majority of the title compound precipitated upon cooling and could be isolated in sufficiently pure form by filtration. A small additional amount of the desired product was obtained by workup of the mother liquor (evaporation of solvent, column chromatography [silica gel, solvent gradient n-heptan/ethyl acetate=100/0−60/40]). The title compound was obtained in a combined yield of 1.46 g (43%).
