The 20H24N2O2S, contains two independent molecules having very similar geometries. The main N-(6-methoxy-1,3-benzothiazol-2-yl)acetamide moiety adopts an almost planar structure (r.m.s. deviations of 0.091 and 0.051 Å for the two independent molecules). The adamantyl substituent occupies the gauche position relative to the C—N bond of the acetamide moiety [the corresponding N–C–C–C dihedral angles are −100.3 (3) and −96.5 (3)° for the two independent molecules]. In the crystal, the two independent molecules form a dimer via a pair of N—H⋯N hydrogen bonds. The dimers are further linked by C—H⋯O hydrogen bonds and attractive S⋯S [3.622 (2) Å] interactions into ribbons along [100].

A mixture 1-(1-adamantylacetyl)-1H-imidazole (1.06 g, 4.3 mmol) and 6-methoxy-1,3-benzothiazol-2-amine (0.9 g, 4.9 mmol) in CHCl3 (50 ml) were refluxed for 6 h. The precipitate was filtered, and then reaction mixture was concentrated in vacuo. The residue crystallized from 80% EtOH. Yield is 22%. The single crystals of the product I was obtained by slow crystallization from EtOH. M.p. = 485-486 K. IR (KBr), ν/cm-1: 3178, 2903, 2848, 1668, 1604, 1472, 1267, 1062, 827. 1H NMR (500 MHz, DMSO-d6, 304 K): δ = 1.52-1.49 (m, 6H), 1.66-1.63 (m, 6H), 1.96-1.93 (m, 3H), 2.63-2.61(m, 2H), 3.76 (s, 3H), 7.03-7.01 (m, 1H), 7.35-7.34 (m, 1H), 7.73 (dd, 1H, J = 8.87). Anal. Calcd for C20H24N2O2S: C, 67.38; H, 6.79. Found: C,67.32; H, 6.82.
The hydrogen atoms of the amino groups were localized in the difference Fourier map and included in the
with fixed positional and isotropic displacement parameters - Uiso(H) = 1.2Ueq(N). The other hydrogen atoms were placed in the calculated positions with C–H = 0.95Å (for aryl H), 0.98Å (for methyl H), 0.99Å (for methylene H), 1.00Å (for methine H) and refined in the riding model with fixed isotropic displacement parameters: Uiso(H) = 1.5Ueq(C) for the CH3 groups and 1.2Ueq(C) for the other CH groups.Data collection: APEX2 (Bruker, 2005); cell

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

Benzothiazoles are important and versatile building blocks in organic synthesis, in particular, for production of various biologically active compounds in medicinal and industrial fields (Gupta & Rawat, 2010; Facchinetti et al., 2012; Sareen et al., 2012; Radatz et al., 2013). Notably, among all benzothiazole derivatives, 2-substituted benzothiazoles are of special interest due to their multiple applications as medicinal agents, agrochemicals, materials for chemical sensors etc. (Hussein et al., 2012; Ugale et al., 2012; Yoo et al., 2012; Zhu et al., 2012; Bhardwaj et al., 2013; Patel et al., 2013).
In this work, a 2-(1-adamantyl)-N-(6-methoxy-1,3-benzothiazol-2-yl)acetamide, C20H24N2O2S, (I) was prepared by the reaction of 1-(1-adamantylacetyl)-1H-imidazole with 6-methoxy-1,3-benzothiazol-2-amine (Fig. 1) and its structure was unambiguously established by the X-ray diffraction study.
Compound I crystallizes in the triclinic P1 space group with two crystallographically independent molecules forming an H-bonded dimer by the two classical intermolecular N–H···N hydrogen bonds (Table 1, Fig. 2). The geometries of these two independent molecules are very similar. The main N-(6-oxy-1,3-benzothiazol-2-yl)acetamide fragment adopts almost planar structure determined by the long chain of conjugated bonds. The adamantyl substituent occupies the gauche position in relative to the C–N bond of the acetamide moiety (the corresponding N–C–C–C dihedral angles are -100.3 (3)° and -96.5 (3)° for the two independent molecules, respectively).
In the crystal, the H-bonded dimers of I are linked by the intermolecular C6–H6···O3i and C26–H26···O1ii non-classical hydrogen bonds (Table 1) as well as attractive S1···S2i (3.622 (2)Å) interactions into ribbons toward [100] (Fig. 3). Symmetry codes: (i) x+1, y, z; (ii) x-1, y, z.
