Reaction Steps

The solution of 3-fluoro-4-nitrophenol (1 g, 6.37 mmol) in aqueous MeNH2 solution (5 mL) was stirred at 85° C. for 5 h. After cooling to room temperature, the solution was diluted with water (30 mL) and concentrated HCl added to adjust to pH 1. The resulting precipitate was collected by filtration and the solid dried under vacuum to give the crude product which was used without further purification (1.1 g, 95% yield). LCMS (m/z): 169.1 (M+1).
