| | 3-AMINO-5-BROMOBENZOIC ACID Usage And Synthesis |
| Uses | peptide synthesis | | reaction suitability | reaction type: solution phase peptide synthesis | | Synthesis | The general procedure for the synthesis of 3-amino-5-bromobenzoic acid from 3-bromo-5-nitrobenzoic acid was as follows: concentrated hydrochloric acid (30 mL) was slowly added to a solution containing 3-bromo-5-nitrobenzoic acid (7.02 g, 28.54 mmol) and ethanol (150 mL), and the mixture was stirred for 5 min at room temperature. Subsequently, tin (II) chloride was added and the reaction mixture was stirred at 50 °C for 2 hours. After completion of the reaction, the mixture was cooled to room temperature. The pH was adjusted to 9 with 8 M sodium hydroxide solution, at which point a solid precipitated. The solids were removed by filtration. The filtrate was acidified to pH 5 with hydrochloric acid and the target product 3-amino-5-bromobenzoic acid was precipitated, which was filtered to give 5.8 g (94% yield). The product was analyzed by HPLC/MS with a retention time of 4.67 min, LRMS: m/z 216 (M-1). | | References | [1] Patent: EP2196465, 2010, A1. Location in patent: Page/Page column 42; 43
