In the title compound, C(13)H(14)N(2)O, the N(pyrrole)-C(H(2))-C-C torsion angle is -7.7 (3)° and the dihedral angle between the pyrrole and benzene rings is 83.6 (2)°. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains extending along the c axis. We have previously reported another polymorphic form of this title compound, which has the same space group with different cell parameters: a = 9.8285 (18) Å, b = 23.588 (4) Å, c = 9.9230 (17) Å, β = 90.107 (3)°, Z = 8 and V = 2300.5 (7) Å(3) [Zeng et al. (2010 ▶). Acta Cryst. E66, o2051].
在标题化合物C(13)H(14)N(2)O中，N（吡咯）-C(H(2))-C-C扭转角为-7.7 (3)°，吡咯环与苯环之间的二面角为83.6 (2)°。在晶体中，分子间的N-H⋯O氢键将分子连接成沿c轴延伸的链。我们之前报道过该标题化合物的另一种多晶型形式，它具有相同的空间群但晶胞参数不同：a = 9.8285 (18) Å，b = 23.588 (4) Å，c = 9.9230 (17) Å，β = 90.107 (3)°，Z = 8且V = 2300.5 (7) Å(3) [曾等人（2010年▶）。《晶体学报E辑》66卷，o2051]。
