Participants

Reaction Steps

A mixture of 3-benzoyl-7-bromo-1,2,3,4,5,6-hexahydroazepino[4,5-b]indole (0.517 g, 1.40 mmol), potassium carbonate (0.77 g, 5.60 mmol), phenylboronic acid (0.194 g, 1.54 mmol), tetrakis(triphenylphosphine)palladium (0.16 g, 0.14 mmol) in tetrahydrofuran (7.0 mL) and N,N-dimethylacetamide (7.0 mL) was stirred at room temperature overnight. The mixture was filtered through Celite and the filtrate concentrated in vacuo to give an oil, which was subjected to column chromatography (silica gel, 10-50% EtOAc/heptane) to afford 0.44 g (86%) of the title compound as a solid: mp 198-200° C.; 1H NMR (400 MHz, CDCl3) δ 8.10, 7.67-7.60, 7.55-7.4, 7.47-7.33, 7.18-7.14, 4.04-3.96, 3.72-3.63, 3.20-3.12, 2.93-2.80; IR (drift) 3258, 1602, 1464, 1430, 1327, 1295, 1239, 1185, 930, 761, 749, 740, 711, 703, 696 cm−1; MS (EI) m/z 366 (M+); HRMS (FAB) calcd for C25H22N2O+H: 367.1810, found: 367.1805; Anal. Calcd. for C25H22N2O: C, 81.94; H, 6.05; N, 7.64. Found: C, 81.37; H, 6.12; N, 7.57.
