Reaction Steps

8-Chloro 2-methyl-2,3,4,5-tetrahydro-1H-pyrido (4,3-b) indole (200 mg, 0.909 mmol), copper (I) iodide (17.2 mg, 0.09 mmol), L-proline (20.9 mg, 0.1818 mmol), Potassium phosphate tribasic (385 mg, 1.818 mmol) were charged in DMF (3 mL) and stirred for 5 min. 2-(2-bromo-1-methyl-vinyl))-5-methyl pyrazine (210 mg, 0.0.999 mmol) was added and nitrogen gas purged into the reaction mixture for a min. The resulting solution was stirred at RT for 5 min followed by heating at 90° C. for 14 h. After completion of the reaction, DMF was evaporated, water was added and the reaction mixture filtered. The crude product was purified by reverse phase HPLC to obtain 40 mg desired product. 1H NMR (CDCl3, free base) δ (ppm): 8.70 (s, 1H), 8.50 (s, 1H), 7.58 (s, 1H), 7.40 (s, 1H), 7.18 (d, 1H), 7.10 (d, 1H), 3.90 (s, 2H), 3.10 (m, 2H), 3.0 (m, 2H), 2.75 (s, 3H), 2.60 (s, 3H), 2.05 (s, 3H).
