Reaction Steps

8-Ethyl-2-methyl-2,3,4,4a,5,9b-hexahydro-1H-pyrido[4,3-b]indole (200 mg, 0.9345 mmol), potassium phosphate (396 mg, 1.8 mmol), copper (I) iodide (21 mg, 0.18 mmol), L-proline (17 mg, 0.09345 mmol) and 4-(1-bromoprop-1-en-2-yl)pyridine (277 mg, 1.40 mmol) were mixed in DMF and the reaction mixture was purged with nitrogen. The contents were cooled to RT and poured into water. The precipitate obtained was filtered, dried and purified by HPLC. 1H NMR (CD3OD, TFA salt) δ (ppm): 8.58 (d, 2H), 7.70 (d, 2H), 7.36 (s, 1H), 7.22 (s, 1H), 7.05 (m, 2H), 3.75 (s, 2H), 2.95 (m, 2H), 2.85 (m, 2H), 2.70 (q, 2H), 2.38 (s, 3H), 2.00 (s, 3H), 1.25 (t, 3H).
