Abstract: In the crystal of the title compound, C₁₁H₁₅NO₄, the molecules are linked into sheets by N-HO and C-HO hydrogen bonds. Within the molecule, the 1,4-dihydropyridine ring exhibits a distinctive planar conformation [r.m.s. deviation from the mean plane of 0.009 (3)Å], and the other non-H atoms are almost coplanar [r.m.s. deviation = 0.021 (3) Å] with the 1,4-dihydropyridine ring. The conformation of the latter is governed mainly by two intramolecular C-HO non-classical interactions.
