Reaction Steps
Fe Powder (4.33 g, 77.4 mmol) was added to a solution of 3-(methylamino)-4-nitrophenol (1.3 g, 7.74 mmol) in HCOOH (30 mL) and the mixture heated to 100° C. for 16 h. After cooling to room temperature, MeOH (250 mL) was added to mixture and filtered over a pad of Celite. The filtrate was collected, concentrated and the residue purified by column chromatography to give the crude desired product (1.2 g) and was used directly in the next step. LCMS (m/z): 149.06 (M+1).
