The title compound, C13H19N3O2, was obtained by the direct solvent-free reaction of 4-hydroxy-3-methoxybenzaldehyde with 1-amino-4-methylpiperazine. The piperazine ring adopts a chair conformation. In the crystal, strong intermolecular O—H⋯N and weak intermolecular C—H⋯O and C—H⋯N hydrogen bonds help to establish the packing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
