The title compound, C10H13NO, was obtained as the
unexpected, almost exclusive, product in the attempted synthesis of a manganese(I)–N-heterocyclic carbene (NHC) complex. The dihedral angle between the planes of the formamide moiety and the aryl ring is 68.06 (10) . In the crystal, molecules are linked by N—H O hydrogen bonds,
forming infinite chains along the c axis.
