This compound has unique chemical properties. The synthetic route is as follows. COA of Formula: C6H6N2O3
Method 4 Synthesis of 7-methoxy-1H-pyrrolo[2,3-c]pyridine (Intermediate 5) A solution of R-4 (500 mg, 3.24 mmol) in anhydrous THF (20 mL) is cooled to -78° C. and vinylmagnesium bromide (9.73 mL of a 1 M solution in THF, 9.73 mmol) added. The reaction is stirred at -20° C. for 6 h then quenched with saturated aqueous NH4Cl solution and extracted with EtOAc. The organic phase is concentrated in vacuo and the crude material purified by flash chromatography (SiO2, 2percent to 10percent MeOH in DCM) to give the title intermediate I-5 (100 mg) m/z 148.9 [M+H].
