Abstract

In the isoquinoline ring system of the title mol­ecule, C19H24N2O6, the N-heterocyclic ring is in a half-boat conformation. The mol­ecular structure is stabilized by an intra­molecular O—H⋯O hydrogen bond, which generates an S(7) ring motif. In the crystal, mol­ecules are linked via inter­molecular bifurcated N—H⋯(O,O) and weak C—H⋯O hydrogen bonds into a three-dimensional network.
