반응 단계

Acetic anhydride (15.2 ml, 0.16 mol) was added dropwise to a stirred mixture of 4-bromo-2-methylaniline (10.0 g, 0.054 mol) and sodium acetate (2.52 g, 0.056 mol) in toluene (150 ml). Once the addition was complete the mixture was warmed to 85° C. and stirred for 40 minutes. The mixture was cooled to room temperature, diluted with ethyl acetate and washed with water. The organic solution was evaporated in vacuo, a further quantity of toluene was added and then the solvent was evaporated to give 4-bromo-2-methylacetanilide (12.3 g), as a colourless solid.
