Reaction Steps

Methyl 4-(3-methoxyphenyl)-1H-pyrrolo[3,2-c]pyridine-2-carboxylate (50 mg, 0.177 mmole) and K2CO3 (49.0 mg, 0.354 mmole) were combined in a screw cap vial. To this was added 1,4-dioxane (0.75 mL) and 1-bromo-3-phenylpropane (0.035 mL, 0.230 mmole). The vial was capped then heated to 100° C. After stirring overnight the mixture was cooled to RT and diluted with EtOAc. The mixture was filtered through Celite washing with EtOAc. The filtrate was concentrated. Flash column (Biotage-SNAP-10 g SiO2, 30% EtOAc/hexanes) gave the title compound (68 mg, 96%) as a pale yellow oil. 1H NMR (399 MHz, CDCl3): δ 8.46 (d, J=6.0 Hz, 1 H); 7.58 (d, J=1.0 Hz, 1 H); 7.55-7.50 (m, 2 H); 7.48-7.39 (m, 1 H); 7.32-7.27 (m, 2H); 7.23-7.17 (m, 3 H); 7.09 (dd, J=6.0, 1.0 Hz, 1 H); 7.02 (ddd, J=8.2, 2.7, 1.1 Hz, 1 H); 4.65-4.57 (m, 2 H); 3.91 (m, 6 H); 2.76-2.68 (m, 2 H); 2.21-2.13 (m, 2 H).
