Versuchsvorschrift

8-Chloro-2-methyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (100 mg, 0.45 mmol) was dissolved in toluene (5 mL). Copper sulfate (23 mg, 0.090 mmol), 1,10-phenanthroline (33 mg, 0.18 mmol), potassium phosphate (192 mg, 0.90 mmol), and 4-(bromoethynyl)-2-fluoro-1-methoxybenzene (113 mg, 0.49 mmol) were added, and the mixture was flushed with nitrogen. The reaction mixture was heated at 80° C. overnight (16 h). Product was detected by LCMS. The reaction mixture was filtered through Celite, and washed with DCM. The combined organic layer was concentrated under reduced pressure to obtain product, which was purified by column chromatography using silica gel and 60-80% EtOAc in hexane as eluent, and repurified by preparative TLC to obtain product as a brown solid (20 mg). 1H NMR (DMSO, oxalate salt) δ (ppm): 7.70 (d, 2H), 7.58 (d, 1H), 7.42 (d, 1H), 7.38 (d, 1H), 7.25 (m, 1H), 4.20 (m, 2H), 3.85 (s, 3H), 3.40 (m, 2H), 3.10 (m, 2H), 2.80 (s, 3H).
