Abstract: In the title compound, C₁₆H₁₅N₃O₃, the dihedral angle between the approximately planar benzimidazolyl group (r.m.s. deviation = 0.010 Å) and the pyrrolidine ring is 78.20 (6)°. The C-C-N bond angle of the bridging CH₂ group is 112.14 (16)°. In the crystal, molecules are linked via N-HN hydrogen bonds, forming infinite chains parallel to [101] and [10].
