Ethyl 7-pivaloyl-amino-1,8-naphthyridine-2-carboxyl-ate sesquihydrate.
In the title hydrate, C(16)H(19)N(3)O(3)·1.5H(2)O, both water mol-ecules are disordered: one over two adjacent sites in a 0.498 (5):0.502 (5) ratio and one lying near a crystallographic twofold axis. The dihedral angle between the pyridine rings of the organic moleucle is 1.47 (6)°. In the crystal, the components are linked by N-H⋯O, O-H⋯N and C-H⋯O hydrogen bonds, forming sheets lying parallel to the ac plane.
