Versuchsvorschrift

6-chloro-2-methyl-2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole (100 mg, 0.45 mmol) was mixed with CuSO4.5H2O (23 mg, 0.090 mmol), 1,10-phenanthroline (33 mg, 0.18 mmol), K3PO4 (192 mg, 0.90 mmol) and 4-(bromoethynyl)-2-fluoro-1-methoxybenzene (113 mg, 0.49 mmol) in toluene (5 ml). The reaction mixture was purged with nitrogen and heated at 80° C. for 16 h. Product was detected by LCMS. The reaction mixture was filtered through Celite and Celite bed was rinsed with dichloromethane. Combined organic layer was concentrated under reduced pressure and the residue was purified by silica gel chromatography (100-200 mesh) eluting with 60-80% ethyl acetate in hexane to obtain 6-chloro-9-((3-fluoro-4-methoxyphenyl)ethynyl)-2-methyl-2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole (30 mg). 1H NMR (CDCl3) FREE BASE 7.42 (d, 2H), 7.25 (m, 3H), 6.95 (t, 1H), 3.90 (s, 3H), 3.70 (s, 2H), 2.80 (m, 4H), 2.56 (s, 3H).
