The resultant mixture was stirred overnight at room temperature. The reaction was quenched with water. EtOAc was added and the layers were separated. The aqueous layer was extracted with EtOAc twice. The combined organic layers were washed with water and brine successively, then dried (Na2SO4), filtered, and concentrated (then triturated with cold EtOAc) to give the desired product as a light brown gel (2.82 g, 91%). LCMS for C14H16Cl2N3O (M+H)+: m/z=312.0, 314.0.
