(E)-3-[(Di­methyl­amino)­methyl­idene]-4-phenyl-1H-1,5-benzodiazepin-2(3H)-one

Abstract

The asymmetric unit of the title compound, C₁₈H₁₇N₃O, consists of two independent mol­ecules, each having an E conformation with respect to the C=C bond between the benzodiazepinone and di­methyl­amine groups. In the crystal, the two independent mol­ecules are linked into a dimer by a pair of N—H⋯O hydrogen bonds.

1. Comment

The benzodiazepine nucleus is a pharmacophoric scaffold and represents a class of heterocycles with a wide range of applications. In particular, several representative benzodiazepines possess significant biological activity as antiviral (Di Braccio et al., 2001), antipsychotic agents (Kavita et al., 1988) and may be considered support for the synthesis of more active heterocyclic systems. Research in this area is highly active being directed towards the synthesis of compounds with enhanced pharmacological activity. Following the research efforts from some of us concerning novel synthetic pathways of new benzodiazepines (Loughzail et al., 2014).

The reaction of N,N-dimethylformamide dimethylacetal (DMF-DMA) in 4-phenyl-1H-1,5-benzodiazepin-2(3H)-one (Nardi et al., 1973) at reflux leads to the formation of the title compound, (E)-3-[(dimethylamino)methylene]-4-phenyl-1H-1,5-benzodiazepin-2(3H)-one with a good yield of 75%. The main geometric feature determined by X-ray diffraction is in good agreement with that observed in a similar compound (Loughzail et al., 2014).

2. Experimental

A mixture of 0.47 g (1.98 mmol) of 4-phenyl-1H-1,5-benzodiazepin-2(3H)-one in 4.5 ml of dimethylformamide-dimethylacetal (DMF-DMA) was stirred at 100 °C for 4 h and then cooled to ambient temperature. Filtration and washing with a little cold diethyl ether gave 0.46 g of (E)-3-[(dimethylamino)methylene]-4-phenyl-1H-1,5-benzodiazepin-2(3H)-one. The product obtained was recrystallized from diethyl ether. Yield: 75%. Melting point: 497–498 K. ¹H NMR (CDCl₃, 300 MHz): δ 2.55 (s, 6H, (CH₃)₂N), 2.80 (s, 1H, NH), 6.32 (s, 1H, C=CH—N), 7.04–7.92 (m, 9H, H—Ar); ¹³C NMR (CDCl₃, 75 MHz): δ 43.50 (N(CH₃)₂), 98.02 (C=), 121.47–141.86 (12 C-Ar), 151.18 (CH—N(CH₃)₂), 167.40 (Ph—C=N), 178.57 (CO). MS (m/z, %): 292 ([M+H]⁺.

3. Refinement

All H-atoms were located in a difference map and then refined using a riding model with N—H = 0.86 Å and C—H = 0.93–0.96 Å, and with U_iso(H) = 1.2U_eq(N, C) or 1.5U_eq(C_methyl).

Special details

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.
