摘　　要：The title compound （C20H21N3O4, Mr = 367.40） has been synthesized and its crystal structure was determined by single-crystal X-ray diffraction. The crystal is of orthorhombic, space group P212121 with a = 7.5143（15）, b = 13.901（3）, c = 18.545（4）A , V = 1937.1（7） A^3, Z = 4, Dc = 1.260 g/cm^3, μ = 0.089 mm^-1, F（000） = 776, the final R = 0.0616 and wR = 0.0912. X-ray diffraction reveals that the molecule adopts an E configuration about the central C=N double bond. The intermolecular O-H…O hydrogen bond stabilizes the crystal structure by causing the formation of a supramolecular architecture.The title compound （C20H21N3O4, Mr = 367.40） has been synthesized and its crystal structure was determined by single-crystal X-ray diffraction.
