Reaction Steps
5-(-1-Bromoprop-1-en-2-yl)-2-methoxypyridine (50 mg, 0.25 mmol) was dissolved in DMF (2 mL). Potassium phosphate (106 mg, 0.5 mmol) was added followed by copper (I) iodide (4 mg, 0.02 mmol) and L-proline (5 mg, 0.04 mmol). 2,3,4,5-Tetrahydro-2,8-dimethyl-1H-pyrido[4,3-b]indole (50 mg, 0.25 mmol) was added under nitrogen (Nitrogen purged for 2 min). The reaction mixture was stirred at 85° C. overnight. Water (15 mL) was added and compound extracted with EtOAc (3×30 mL). The organic layer was concentrated under vacuum and purified through reverse phase chromatography. Yield: 3.87 mg (TFA salt). 1H NMR (CD3OD, TFA salt) δ (ppm): 8.30 (s, 1H), 7.90 (d, 1H), 7.20 (s, 1H), 7.02 (d, 1H), 6.99 (d, 1H), 4.62 (m, 1H), 4.30 (m, 1H), 3.86 (s, 3H), 3.78 (m, 1H), 3.50 (m, 1H), 3.05 (m, 2H), 3.02 (s, 3H), 2.38 (s, 3H), 1.82 (s, 3H).
