実験手順

2,8-Dimethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (200 mg, 1 mmol) was dissolved in DMF. Copper (I) iodide (19 mg, 0.1 mmol), L-proline (23 mg, 0.2 mmol) and potassium phosphate (424 mg, 2 mmol) were added and the reaction mixture was stirred for 10 min. at RT. 1-(1-Bromoprop-1-en-2-yl)-2-chlorobenzene (277 mg, 1.2 mmol) was added dropwise and the reaction mixture was purged with nitrogen. The reaction mixture was heated overnight at 85° C. (prolonged heating in some cases was required). DMF was evaporated under reduced pressure, the residue was diluted with water and the solid was filtered. The solid material was purified by silica gel chromatography (100-200 mesh) eluting with 0-5% MeOH-DCM. Yield: 0.37 mg as the TFA salt. 1H NMR (CDCl3, TFA salt) δ (ppm): 7.25 (m, 2H), 7.10 (t, 1H), 7.05 (s, 1H), 7.0 (m, 2H), 6.90 (d, 1H), 6.75 (s, 1H), 4.40 (d, 1H), 4.0 (d, 1H), 3.40 (m, 1H), 3.20 (m, 1H), 2.90 (m, 1H), 2.80 (s, 3H), 2.65 (m, 1H), 2.40 (s, 3H), 2.30 (s, 3H).
