実験手順

386 mg 2-Aminoanthracene and 434 mg 4-dimethylamino-4-phenyl-cyclohexanone were dissolved in dry 1,2-dichloroethane (20 ml) under argon. Glacial acetic acid (2 mmol) and 600 mg sodium triacetoxyborohydride were added to this mixture and the mixture was stirred for 24 hours at RT. For working up, the reaction mixture was concentrated and the residue was adjusted to pH 11 with five molar sodium hydroxide solution and extracted with ethyl acetate (4×20 ml). The combined extracts were dried over sodium sulfate and filtered and the filtrate was concentrated. The crude products was chromatographed over silica gel with ethyl acetate/ethanol (1:1). 132 mg of the nonpolar diastereomer of N′-anthracen-2-yl-N,N-dimethyl-1-phenyl-cyclohexane-1,4-diamine were obtained as a green solid, from which the corresponding hydrochloride was precipitated with 1.85 M ethanolic hydrochloric acid (0.46 ml) in 2-butanone (5 ml) (104 mg; m.p. 169-172° C.).
