The reaction was stirred at 0° C. for 1 hr and then warmed slowly to room temperature. The reaction mixture was diluted with water. The layers were separated and the organic layer was washed with brine, dried over MgSO4, filtered, and the organic phase stripped to dryness via rotary evaporation. The organic extract was dried in vacuo to provide N-ethyl-4-fluorobenzamide (21 g, 100% yield) as a tan solid.
