The title compound, C11H13BN2O4, has a rigid bicyclic structure due to an intramolecular nitrogen–boron dative bond. The B atom is in a distorted tetrahedron environment with a B—N bond length of 1.640 (2) Å, which is in good comparison with the values in analogues compounds. In the crystal, the molecules are linked by weak C—HO and C—HN interactions, forming a three-dimensional network.
