Reaction Steps

Pyridine (500 uL, 6.19 mmol) was added to a solution of 4-fluoro-3-nitro-phenylamine (1 g, 6.41 mmol) and 4-fluoro-benzenesulfonyl chloride (1.2 g, 6.19 mmol) in dichloromethane (DCM) (20 mL) and the reaction was stirred at room temperature overnight. The reaction was then partitioned between water and DCM. The organic layer was washed several times with water and concentrated. Recrystalization from ethanol/water gave 1.57 g of the sub-title compound as tan crystals.
