Reaction Steps

In an atmosphere of argon, 25 g (145.3 mmols) of 4-bromoaniline was dissolved in 50 ml of methanol, and the solution obtained was cooled to 0° C., and thereafter 27.4 ml (2.0-fold equivalent weight) of acetic anhydride was dropwise added thereto. Thereafter, the solution obtained was restored to room temperature, and stirred for 20 minutes. To the reaction solution obtained, 250 ml of water was added, and a white solid deposited was collected by filtration, which was then washed with water, followed by natural drying to obtain 30.8 g of N-acetyl-4-bromoaniline (yield: 99.1%; a while solid).
