Abstract: In the title compound, C20H24N2O5, the dihedral angle between the two roughly planar salicyl­amide fragments [r.m.s. deviations = 0.043 (2) and 0.149 (2) Å] is 25.50 (5)°. The mol­ecular conformation is stabilized by intra­molecular O-H...O hydrogen bonds involving phenol -OH groups and amide O atoms. Inter­molecular hy­droxy­meth­yl-amide O-H...O and amine-hy­droxy­methyl N-H...O hydrogen bonds form infinite chains along the b axis. These chains are further inter­linked by amine-amide N-H...O and phenol-phenol O-H...O inter­actions, thus giving layers parallel to (001).
