In the title compound, C22H24N2O2·H2O, the co-crystallized water molecule interacts with the N and O atoms of the molecule through Ow—H⋯N, Ow—H⋯O(methyl) and N—H⋯Ow hydrogen-bonding interactions. These hydrogen bonds, along with the intermolecular N—H⋯O=C hydrogen-bonding interactions, connect the molecules into a three-dimensional network. The dihedral angle between the two aromatic rings is 65.46 (10)°.

A mixture of dimedone (2.0 g, 14.3 mmol) and o-phenylenediamine (1.54 g, 14.3 mmol) in absolute ethanol (30 ml), containing acetic acid (0.5 ml), in a beaker was pulse irradiated in a microwave oven for 5 min. and left to stand at room temperature for 1 h. Anisaldehyde (1.95 g, 14.3 mmol) was added to the reaction mixture and then subjected to microwave irradiation for 5 min. (TLC monitored). Evaporation of the solvent afforded a gummy product. Cold aqueous ethanol was added with scratching to give yellow precipitate (melting point 202–205 o C). Crystals of 1 suitable for X-ray analysis were obtained by slow evaporation of ethanol solution of the product.
The H atoms of the water molecule were located on a Fourier difference map, restrained by DFIX command 0.85 for O—H distances and by DFIX 1.39 for H···H distance, and refined as riding with Uiso(H) = 1.5Ueq(O). Other atoms were placed in their calculated positions, with C—H = 0.93 or 0.96 Å, and refined using a riding model, with Uiso(H) = 1.2 or 1.5Ueq(C).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Dibenzo[b,e][1,4]diazepinones are useful intermediates in the synthesis of pharmaceuticals. For example, dibenzo[b,e][1,4]diazepin-11-ones are useful intermediates in the preparation of dibenzo[1,4]diazepines (Hanze et al., 1963). They display wide variety of biological properties, including antidepressant (Beccalli et al., 2005), antimicrobial (Farnet et al., 2005), analgesic and anti-inflammatory (Joergensen et al., 1996), antitumor (McAlpine et al., 2008) activities, while the dibenzodiazepin-1-ones are hepatitis C virus (HCV) NS5B polymerase inhibitors (McGowan et al., 2009). In view of our interest in bioactivity of nitrogen-containing heterocyclic compounds (see: Ajani et al., 2010), we report here the microwave-assisted synthesis and the crystal structure of the title compound 1.
