| Sumario: | The title compound, C(21)H(26)N(2)O(3), crystallizes with two independent molecules in the asymmetric unit. In both independent molecules, the diazepine ring adopts a chair conformation. In the crystal, the independent molecules exist as N—H⋯O hydrogen-bonded R (2) (2)(8) dimers which are linked via N—H⋯O hydrogen bonds, forming tetramers. The tetramers are linked by C—H⋯O hydrogen bonds. In one of the molecules in the asymmetric unit, the terminal C atom of the ethyl group is disordered over two positions with refined occupancies of 0.742 (4) and 0.258 (4). |
