The title compound, C(21)H(26)N(2)O(5), was unexpectedly obtained as a by-product in the reaction of ethyl acetoacetate, 4-acetamido-benzaldehyde and urea under microwave irradiation. The dihydro-pyridine ring assumes a flattened boat conformation. Inter-molecular N-H⋯O and weak C-H⋯O hydrogen bonding occurs in the crystal.
标题化合物C(21)H(26)N(2)O(5)是在乙酰乙酸乙酯、4-乙酰氨基苯甲醛和尿素在微波辐射下反应时意外得到的副产物。二氢吡啶环呈扁平船式构象。晶体中存在分子间N-H⋯O和弱C-H⋯O氢键。
