Procedure
4-Fluoro-3-nitrobenzonitrile (0.25 g, 1.5 mmol) was cautiously added to a solution of methylamine (2.0 M, 5.0 mL) in THF. The mixture was stirred at room temperature for 8 h, concentrated under reduced pressure, and chromatographed (silica gel, DCM) to give the title product (0.18 g, 68%) as a yellow solid. 1H-NMR (CDCl3): δ 8.52 (1H, d), 8.41 (1H, br s), 7.64 (1H, dd), 6.92 (1H, d), 3.10 (3H, d).
