Reaction Steps

3-bromo-2-methylbenzoic acid (5.00 g, 23.3 mmol) was dissolved in DMF (41.6 ml) and EDC (5.46 g, 28.5 mmol), HOAt (3.97 g, 29.2 mmol), ammonium chloride (4.90 g, 90.9 mmol), and diisopropylethylamine (12.5 ml, 71.8 mmol) were added. The reaction was stirred at room temperature over the weekend, and then poured into water (100 ml). The resultant precipitate was filtered, washed with water, collected, and dried under vacuum to give the title compound (4.63 g, 93%). MS (ESI pos. ion) m/z: 214 (M+H). Calc'd Exact Mass for C8H8BrNO: 213.
