摘要：
The title compound, C30H29N3O3 . H2O, is the final product in the Diels-Alder reaction between a 2-alkoxydiene and a reactive dienophile such as phenyltriazolinedione after recrystallization from methanol. The water molecule forms a hydrogen bond with a carbonyl O atom in one dione molecule and a weaker interaction with an N atom in a symmetry-related molecule, forming dimers linked by the water molecule. Atoms in the five-membered ring stemming from the dienophile molecule are related by a non-crystallographic C-2 axis through an N atom.
