Reaction Steps

6-chloro-2-methyl-2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole (75 mg, 0.34 mmol) was dissolved in DMF (5 mL). To this solution was added CuI (6 mg, 0.034 mmol), L-proline (8 mg, 0.068 mmol), K3PO4 (145 mg, 0.68 mmol). The reaction mixture was stirred for 10 min at room temperature followed by addition of 4-(1-bromoprop-1-en-2-yl)-2-fluoro-1-methoxybenzene (100 mg, 0.408 mmol). The reaction mixture was heated at 80° C. overnight. Solvent was evaporated under reduced pressure, the residue was diluted with brine and extracted with ethyl acetate. Organic layer was dried over Na2SO4, and concentrated under reduced pressure. The crude product was purified by silica gel chromatography to obtain 40 mg of 6-chloro-9-(2-(3-fluoro-4-methoxyphenyl)prop-1-enyl)-2-methyl-2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole. 1H NMR (DMSO) OXALATE SALT 7.60 (m, 2H), 7.42 (d, 1H), 7.25 (d, 2H), 7.18 (t, 1H), 7.10 (s, 1H), 4.10 (m, 2H), 3.90 (s, 3H), 3.50 (m, 2H), 2.95 (m, 2H), 2.78 (s, 3H), 1.82 (s, 3H).
