Chemical context top

Indole derivatives inhibit hepatitis C virus replication through induction of pro-inflammatory cytokines (Lee et al., 2015) and these derivatives act as a new anti-hepatitis C virus agents (Andreev et al., 2015). These derivatives also act as potential mushroom tyrosinase inhibitors (Ferro et al., 2015). Indole derivatives also exhibit anti-proliferative (Parrino et al., 2015), anti-inflammatory (Chen et al., 2015) and anti-tumor (Ma et al., 2015) activities. In view of the many interesting applications of indole derivatives, we synthesized the title compound and report herein on its crystal structure.

Structural commentary top

The molecular structure of the title compound, (I), is illustrated in Fig. 1. The geometry of the indole ring system (N1/C1–C8) in (I) is comparable with those reported for similar structures, namely 1-vinyl-1H-indole-3-carbaldehyde (II) (Selvanayagam et al., 2008) and methyl (2Z)-2-[(2-formyl-3-methyl-1H-indol-1-yl)methyl]-3-(4-methoxyphenyl)-prop-2-enoate (III) (Selvanayagam et al., 2014). The superposition of the indole ring system of (I) with the related reported structures, using Qmol (Gans & Shalloway, 2001), gives an r.m.s. deviation of 0.025 Å between (I) and (II), and 0.030 Å between (I) and (III); see Fig. 2. The indole ring system is planar with an r.m.s. deviation of 0.017 Å [maximum deviation of 0.028 (2) Å for atom C3], and the methyl atom C9 deviates by 0.050 (2) Å from its mean plane. The chlorine atom, Cl1, deviates by 0.008 (1) Å from the benzene ring (C15–C20) to which it is attached. This ring is almost perpendicular to the indole ring system, making a dihedral angle of 87.59 (6)°. The sum of the angles at atom N1 of the indole ring (360°) is in accordance with sp² hybridization. The widening of the C16—C15—C14 bond angle to 125.2 (1)° is due to the short H···H contact (H10B···H16 = 2.10 Å). The mean plane of the methyl methacrylate unit [O1/O2/C10–C14; maximum deviation of 0.015 (2) Å for atom O1] is almost planar with the chlrophenyl ring, making a dihedral angle of 18.98 (17)°, but is normal to the indole ring system with a dihedral angle of 89.96 (5)°.

Supramolecular features top

In the crystal, C—H···π interactions link the molecules, forming C(9) chains propagating along [101]; see Fig. 3 and Table 1. Between the chains there are weak π–π interactions involving inversion-related chlorophenyl rings (C15–C20), stabilizing the molecular packing [centroid-to-centroid distance = 3.851 (1) Å]; see Fig. 4.

Synthesis and crystallization top

Substituted (Z)-methyl-2-(bromomethyl)-3-phenylacrylate (1 mmol), tetra-butyl-ammonium bromide (0.5 mmol), and 50% NaOH (20 ml) were added to a solution of 3-methyl indole (1 mmol) in benzene (55 ml). The mixture was stirred vigorously at room temperature for 5–6 h. The organic layer was separated, washed with water and dried over MgSO₄. The solvent was evaporated under reduced pressure (yield: 70%). Suitable crystals were obtained by slow evaporation of a solution of the title compound in methanol at room temperature.

Refinement top

Crystal data, data collection and structure refinement details are summarized in Table 2. H atoms were placed in idealized positions and allowed to ride on their parent atoms: C—H = 0.93–0.97 Å, with U_iso(H) = 1.5U_eq(C) for methyl H atoms and 1.2U_eq(C) for other H atoms.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
