The structure of the product was confirmed by 1H NMR, 13C NMR, IR, HRMS （ESI） and single-crystal X-ray diffraction. The title compound crystallizes in the monoclinic system, space group P21/c with a = 13.0269（10）, b =6.7251（6）, c = 23.9313（16） A, β = 99.931（6）°, V = 2065.1（3） A3, Z = 4, Dc = 1.366 g/cm3, F（000） = 880,μ = 0.221 mm-1, the final R = 0.0600 and wR = 0.1754 for 1981 observed reflections （I〉 20（/））. X-ray analysis indicates that the chloro-phenyl ring （C（10）℃（15）） and the methyl-substituted benzene ring （C（16）℃（21）） are not coplanar with the nitro-substituted benzene ring （C（1）--C（6））, with the dihedral angle to be 70.78° and 63.72°, respectively.
