Procedure

A mixture of 9-chloro-3-methyl-1,2,3,4,5,6-hexahydroazepino[4,5-b]indole (235 mg, 1 mmol), CuSO4.5H2O (50 mg, 0.2 mmol), 1,10-Phenanthroline (72 mg, 0.4 mmol), K3PO4 (425 mg, 2 mmol) and 1-(bromoethynyl)-4-chlorobenzene (237 mg, 1.1 mmol) in toluene (10 mL) was flushed with nitrogen heated 80° C. for 16 h. The reaction was monitored by LCMS. The reaction mixture was filtered through Celite, washed with DCM. The organic layer was concentrated and purified by column chromatography (silica gel, 60-80% ethyl acetate in hexane) to get 37 mg of product. 1H NMR (CDCl3, HCl salt) δ (ppm): 7.50 (s, 1H) 7.49-7.40 (m, 3H), 7.38-7.32(m, 2H), 7.25-7.20 (d, 1H), 3.22-3.18 (m, 2H), 3.0-2.90 (m, 6H), 2.60 (s, 3H).
