3-Benzyl-10-phenyl-1,2,3,4,5,6-hexahydroazepino[4,5-b]indole → 10-Phenyl-1,2,3,4,5,6-hexahydroazepino[4,5-b]indole

Participants

Reaction Steps

A mixture of 3-benzyl-10-phenyl-1,2,3,4,5,6-hexahydroazepino[4,5-b]indole (0.22 g, 0.62 mmol), glacial acetic acid (2 drops) and Pd/C (10%, 0.11 g) in ethanol (50.0 mL) was reacted in a manner similar to Example 8 to give 0.198 g (90%) of a brown foam. Crystallization from ethyl acetate gave 0.030 g of the title compound as a beige solid: mp>250° C.; 1H NMR (300 MHz, CDCl3) δ 7.97, 7.48-7.36, 7.16, 6.94, 3.12-3.08, 3.02-2.98, 2.87-2.83, 2.47-2.43; IR (drift) 3053, 3025, 2927, 2895, 2833, 1458, 1428, 1415, 1335, 1292, 1262, 790, 760, 751, 703 cm−1; MS (EI) m/z 262 (M+); HRMS (FAB) calcd for C18H18N2+H: 263.1548, found 263.1550.
