The 1,4-dihydro-pyridine ring in the title hydrate, C17H 18BrNO2·H2O, has a flattened-boat conformation, and the benzene ring is occupies a position orthogonal to this [dihedral angle: 82.19 (16)°]. In the crystal packing, supra-molecular arrays mediated by N - H⋯Owater and Owater - H⋯Ocarbonyl hydrogen bonding are formed in the bc plane. A highly disordered solvent mol-ecule is present within a mol-ecular cavity defined by the organic and water mol-ecules. Its contribution to the electron density was removed from the observed data in the final cycles of refinement and the formula, mol-ecular weight and density are given without taking into account the contribution of the solvent mol-ecule.
