A mixture of 9-phenyl-3,4,6,7,9,10-hexahydro-1,8(2H,5H)-acridinedione (5.0 g), sodium borohydride (6.5 g), ethanol (150 mL) and pyridine (50 mL) was heated at 70° C. overnight and cooled to room temperature. The solvent was removed, the residue partitioned between water and ethyl acetate, the organic layer was dried and the solvent removed. Chromatography (methylene chloride/methanol; 98/2) provided the title compound (3.0g) as a white solid. Recrystallization from ethanol/hexane returned analytically pure title compound, mp 252°-254° C., NMR: 1.41-1.51 (m,3, CH2), 1.60-1.88 (m,5, CH2), 2.03-2.13 (m,4, CH2), 2.38-2.44 (m,2, CH2), 4.14 (s,1, CH), 7.04-7.21 (m,5, Ar) 8.34 (s,1, NH); (CI, CH4) MS: m/z=280(M+1). Analysis for C19H21NO.0.2H2O: Calculated: C, 80.64; H, 7.62; N, 4.95; Found: C, 80.84; H, 7.62; N, 4.80.
