Procedure
To a solution of 5-bromo-N1-methylbenzene-1,2-diamine (159 mg), isovaleric acid (0.087 ml) and N,N-diisopropylethylamine (0.41 ml) in DMF (2 ml) was added HATU (316 mg) at room temperature. The mixture was stirred at room temperature under a dry atmosphere (CaCl2 tube) for 3 h. After evaporation of the mixture, the residue was purified by NH silica gel column chromatography (hexane/EtOAc). The resulting residue was stirred in AcOH (2.0 ml) at 80° C. for 1 h. After evaporation, the residue was purified by NH silica gel column chromatography (hexane/EtOAc) to give the title compound (156 mg) as a pale yellow solid.
