Step 2: (0648) To a solution of 2-(2-methoxy-3-nitropyridin-4-yl)-N,N-dimethylethylamine (5.9 g, 26 mmol) prepared in Step 1 in ethanol (275 mL) was added 10% palladium carbon (Degussa type, 1.5 g). The reaction mixture was placed under hydrogen atmosphere (15 psi) and shaken for 15 min. Upon completion of the reaction, the reaction mixture was filtered through a bed of diatomaceous earth and washed with dichloromethane (DCM). The filtrate was concentrated under reduced pressure to afford 7-methoxy-1H-pyrrolo[2,3-c]pyridine (4.3 g, 61% yield).
