Reaction Steps
1-(4-Methoxy-1H-pyrrolo[2,3-c]pyridin-7-yl)-1H-1,2,4-triazole-3-carbonitrile (1 g, 4.16 mmol) and K2CO3 (0.863 g, 6.24 mmol) were combined in MeOH (20 mL) and water (20 mL). The mixture was stirred at room temperature overnight. The mixture was neutralized with 1N HCl to pH=3. The precipitate was collected by filtration to give methyl 1-(4-methoxy-1H-pyrrolo[2,3-c]pyridin-7-yl)-1H-1,2,4-triazole-3-carboxylate (1.03 g, 3.77 mmol, 91% yield). LCMS: m/z 274.2 (M+H)+, 1.63 min (method 8). 1H NMR (500 MHz, MeOD) d ppm 9.22 (s, 1H) 7.47 (s, 1H) 7.39 (d, J=3.05 Hz, 1H) 6.62 (d, J=3.05 Hz, 1H) 4.03 (s, 3H) 4.00 (s, 3H).
