title: Methyl 4-(3-eth-oxy-4-hydroxy-phen-yl)-6-methyl-2-oxo-1,2,3,4-tetra-hydro-pyrimidine-5-carboxyl-ate monohydrate.
abstract: In the title compound, C(15)H(18)N(2)O(5)·H(2)O, the pyrimidine ring adopts a flattened-boat conformation. The eth-oxy group attached to the benzene ring is in an extended conformation. The oxopyrimidine mol-ecules are linked into centrosymmetric R(2) (2)(20) dimers by O-H⋯O hydrogen bonds. The dimers are linked by N-H⋯O hydrogen bonds, forming a two-dimensional network parallel to the bc plane. Adjacent networks are cross-linked via N-H⋯O and O-H⋯O hydrogen bonds involving the water mol-ecules.
