실험 절차

A suspension of methyl 3-bromo-1H-pyrrolo[3,2-c]pyridine-2-carboxylate 12-c (1000 mg, 3.92 mmol), 1-bromo-3-(methylsulfonyl)propane 12-b (804 mg, 3.92 mmol) and cesium carbonate (1277 mg, 3.92 mmol) in dry DMF (8 ml) was heated at 60° C. for 2 hours. The reaction mixture was then cooled to room temperature and poured into iced water. The product was extracted three times with DCM. The combined organic layers were dried over Na2SO4, filtered and evaporated to dryness. The crude was purified by column chromatography using a gradient starting from 0% to 10% MeOH/DCM. After evaporation and drying in vacuo, 750 mg (2.0 mmol, 51.0%) of the target product 12-d was obtained as a white solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 2.10-2.23 (m, 2H) 2.97 (s, 3H) 3.13-3.22 (m, 2H) 3.95 (s, 3H) 4.65 (t, J=7.28 Hz, 2H) 7.75 (dd, J=6.02, 1.00 Hz, 1H) 8.47 (d, J=6.02 Hz, 1H) 8.88 (d, J=1.00 Hz, 1H); m/z=375 (M+H)+, Br pattern.
