Diisobutyl 4-(3-eth-oxy-4-hy-droxy-phen-yl)-2,6-dimethyl-1,4-dihydro-pyridine-3,5-dicarboxyl-ate.

The asymmetric unit of the title compound, C(25)H(35)NO(6), contains two independent mol-ecules. In each mol-ecule, the 1,4-dihydro-pyridine ring adopts a flattened boat conformation. The dihedral angles between the 1,4-dihydro-pyridine and benzene rings are 87.55 (7) and 87.23 (7)°. In one of these mol-ecules, one of the isobutyl groups is disordered over two sets of sites, with an occupancy ratio of 0.890 (2):0.110 (2). In the crystal, mol-ecules are linked through N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds forming two-dimensional networks parallel to the ab plane. The crystal structure is further stabilized by weak C-H⋯π inter-actions.
