Abstract
The title compound, C(11)H(14)N(2)O(5), was synthesized by condensation of (RS)-2-amino-succinic acid dimethyl ester with 2-trichloro-acetyl-pyrrole at room temperature. The amide group is twisted by 7.4 (1)° from the plane of the pyrrole ring. In the crystal, mol-ecules are linked by inter-molecular N-H⋯O hydrogen bonds into chains extending along the c axis.
摘要
标题化合物C(11)H(14)N(2)O(5)是通过在室温下将（RS）-2-氨基琥珀酸二甲酯与2-三氯乙酰基吡咯缩合而成。酰胺基团与吡咯环平面扭转了7.4 (1)°。在晶体中，分子通过分子间N-H⋯O氢键连接成沿c轴延伸的链。
