Reaction Steps

The title compound was synthesized from 4-fluoro-3-nitro-phenylamine (2.00 g, 12.81 mmol) dissolved in THF (25 mL) and Hunig's base (3.312 g, 25.62 mmol) to which was added thiophene-2-carbonyl chloride (1.878 g, 12.81 mmol) drop wise over 10 minutes. Reaction mixture was stirred at room temperature for 1 hr at which time water was added and the title compound was collected by filtration (3.25 g, 95%).
