Reaction Steps

To a solution of 5-chloro-benzene-1,3-diamine (3 g, 21 mmol) and dimethylamino-AcOH (2.2 g, 21 mmol) in CH2Cl2 (300 mL) was added EDC (5 g, 25 mmol), HOBt (2.9 g, 21 mmol), and DIEA (5 mL). The reaction mixture was stirred at RT overnight. Solvent was removed in vacuo and the residue was purified through flash chromatography on silica gel (0-8% MeOH in EtOAc) to give the desired compound.
