2-氨基-5-溴-3-甲基苯酚

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To 1.5 g (7.42 mmol) 2-amino-5-bromo-3-methyl-phenol in 30 mL xylene is added 1.15 mL (8.19 mmol) triethylamine, 0.68 g (2.70 mmol pyridinium p-toluenesulfonate and 0.55 mL (7.74 mmol) acetyl chloride. The mixture is refluxed for 3 d. Subsequently the solvent is removed in vacuo, and the residue is treated with 50 mL ethylacetate. The mixture is extracted twice with water. The combined aq. layers are extracted with ethylacetate. The combines organic layers are dried and concentrated to yield the desired product.
