Dimethyl 3,5-diethyl-1H-pyrrole-2,4-dicarboxylate
نویسندگان
چکیده
The title pyrrole derivative, C(12)H(17)NO(4), consists of a pyrrole ring with two diagonally attached meth-oxy-carbonyl groups and two diagonally attached ethyl groups. The two carbonyl groups are approximately in the same plane as the pyrrole ring, making dihedral angles of 3.50 (19) and 6.70 (19)°. In the crystal, adjacent mol-ecules are assembled into dimers in a head-to-head mode by pairs of inter-molecular N-H⋯O hydrogen bonds.

In the title mol-ecule, C(13)H(19)NO(4), except for two C atoms of the tert-butyl group, the non-H atoms are almost coplanar (r.m.s. deviation = 0.2542 Å). In the crystal, mol-ecules are linked into centrosymmetric dimers by two inter-molecular N-H⋯O hydrogen bonds, forming an R(2) (2)(10) ring motif.
