The reaction was diluted with dichloromethane, washed with water, dried over MgSO4 and then concentrated. The resulted residue was purified on silica gel (eluting with 0 to 5% methanol in dichloromethane) to give the desired product (23 mg, 61%). LCMS calculated for C18H21ClN3O3 (M+H)+: m/z=362.1; Found: 362.0
