Water → N-(2-bromo-3-fluorophenyl)butyramide

Participants

Reaction Steps

To a solution of 2-bromo-3-fluoroaniline (2.0 g, 11 mmol) in CH2Cl2 (50 mL) was added butyryl chloride (1.3 g, 13 mmol) and pyridine (1.7 g, 21 mmol) at 0° C. The mixture was stirred at room temperature for 24 h. Water (20 mL) was added and the mixture was extracted with CH2Cl2 (50 mL×3). The organic layers were dried anhydrous over Na2SO4 and evaporated under vacuum to give N-(2-bromo-3-fluorophenyl)butyramide (2.0 g, 73%), which was directly used in the next step.
