Reaction Steps

A solution of 2-amino-4-bromobenzoic acid (1 g, 4.63 mmol), NH4Cl (1.8 g, 32.41 mmol), TBTU (1.5 g, 4.63 mmol) and diisopropylethylamine (1.2 g, 9.26 mmol) in DMF (30 mL) was stirred at room temperature overnight. Then the mixture was adjusted to pH 8.0 with saturated Na2CO3 and extracted with ethyl acetate (3×50 mL). The combined organic layers were dried over Na2SO4 and concentrated to give the desired yellow product. MS (ESI): 215, 217 (MH+).
