tert-Butyl 6-amino-3,4-dihydro-2H-1,4-benzoxazine-4-carboxylate

The title molecule, C13H18N2O3, contains a benzene ring fused to an oxazine ring and one tert-butoxycarbonyl group bound to the N atom of the oxazine ring. A weak intramolecular C—H...O interaction occurs. In the crystal, intermolecular N—H...O and C—H...O hydrogen bonds stack the molecules down the b axis. Weak C—H...N contacts connect the stacks, generating a three-dimensional network.
