Part A. Synthesis of 2-bromo-4-iodoaniline
The synthesis of this compound is based on a modified method of J. Chem. Soc., Perkin Trans. 1, 1970, 2106. The specific steps are as follows:
1. 1.61 g (9.36 mmol) of o-bromoaniline was mixed with 10 mL of water and 750 mg of sodium bicarbonate solid was added.
2. Mildly heat the mixture using a hot air gun to melt the aniline.
3. 2.58 g (10.2 mmol) of powdered iodine is added in batches over several minutes. 4.
4. Stir the reaction mixture for 2 hours at room temperature. 5.
5. The resulting dark solid product is collected by filtration, washed with water and dried over air to give a slightly wetted dark solid.
6. The product was purified directly by rapid column chromatography on silica gel, eluting first with hexane and subsequently with a hexane solution containing 5% ethyl acetate to afford 2.53 g (91% yield) of the target compound 2-bromo-4-iodoaniline as a pale pink solid. | [References]
