Reaction Steps

To a solution of 2-fluoro-5-nitroaniline (3.0 g, 19.2 mmol) in 24 ml N-methylpyrrolidinone in a sealed reaction vessel was added potassium carbonate (5.4 g, 30.0 mmol) and a solution of methyl amine (20 ml, 2M in THF) and the reaction was heated to 120° C. After 16 h, the reaction mixture was cooled to room temperature and poured into 200 ml of water. The resulting precipitate was filtered and dried to give the title compound as a red solid. MS (ESI) m/z=168 [M+H].
