In the title compound, C(13)H(18)ClNO(4), the two meth-oxy groups at the meta positions of the attached benzene ring are close to being coplanar with the ring [the meth-oxy C atoms deviate by 0.267 (7) and 0.059 (7) Å], whereas the third meth-oxy group at the para position is not coplanar with the benzene ring [methoxy C atom deviates by 1.100 (6) Å]. In the crystal, mol-ecules are linked into a chain along the a axis by O-H⋯N hydrogen bonds.
