    EXP-10 CHEM 233L SYNTHESIS OF p-BROMOANILINE Introduction: In this experiment‚ p-bromoaniline was synthesized in three steps starting from aniline. Since the amino group of aniline is a strong activator of aromatic ring‚ direct bromination is impractical (equation 1). In order to make a desired product‚ amino group needed to be protected as the acetamide which also maintained ortho and para position but slowed down the rate of reaction (equation 2). Slow reaction rate would increase
