Procedure

HATU (4.89 g) was added to a solution of 4-bromo-N2-ethylbenzene-1,2-diamine (2.63 g), N,N-diisopropylethylamine (6.40 ml) and cyclopropanecarboxylic acid (0.979 ml) in DMF (40 ml) at room temperature. The mixture was stirred at room temperature for 1 h. The mixture was quenched with water and extracted with EtOAc. The organic layer was separated, washed with water and brine, dried over MgSO4 and concentrated in vacuo. The residue was dissolved into AcOH (40.0 ml), and the mixture was stirred at 80° C. for 1 h. After concentration of the mixture, the residue was neutralized with saturated NaHCO3 solution and extracted with EtOAc. The organic layer was separated, washed with water and brine, dried over MgSO4 and concentrated in vacuo. The residue was purified by silica gel column chromatography (hexane/EtOAc) to give the title compound (1.2 g) as a pale yellow solid.
