The reaction was diluted with dichloromethane, washed with water, dried over MgSO4 and concentrated. The resulting residue was purified on silica gel (eluting with 0 to 5% methanol in dichloromthane) to give the desired product (21 mg, 27%). LCMS calculated for C19H21ClN3O2 (M+H)+: m/z=358.1; Found: 358.0.
