Abstract: The title compound, C₁₁H₂₃N₃O₅, contains a pyrazole ring and a dihydrofuran ring connected by an NH bridge. The pyrazole ring is planar, while the dihydrofuran ring adopts a twist conformation. The two rings are linked by an intramolecular O-HN hydrogen bond. In the crystal structure, the intermolecular hydrogen-bond network forms chains parallel to the b axis.
