Source of materials

The title compound was synthesized from the Sonogashira Coupling-Aminovinylation Sequence reaction [4]. In a nitrogen atmosphere, a THF solution of phenylacetylene (1.1 mmol in 5 mL THF) was added dropwisely into a stirred mixture of 2-bromo-5-nitrothiazole (1 mmol), Pd(PPh3)2Cl2 (14 mg, 0.02 mmol), CuI (7 mg, 0.04 mmol), and 11 mL of THF/NEt3 (10:1). The reaction mixture was stirred at room temperature overnight until conversion was complete (monitored by TLC). Then, a solution of diethylamine (2 mmol) in 5 mL of methanol was added, and the mixture was heated to reflux for ca. 9 hour until complete conversion (monitored by TLC). The solvents were evaporated in vacuo, and the residue was purified by chromatography over a short pad of aluminum oxide eluting with dichloromethane followed by acetone to yield 60% of the entitled compound. The residue was then recrystallized in dichloromethane by evaporation in vacuo, which yielded dark red crystals. After several attempts a suitable crystal for single X-ray diffraction study was obtained.

Experimental details

H atoms were fixed geometrically at ideal positions and allowed to ride on the parent atoms with C–H = 0.93–0.97 Å, with Uiso(H) = 1.5Ueq(C) (for CH3)and 1.2 Ueq(C) (for CH2 and CH).

Comment

Thiazole derivatives are important heterocyclic compounds for biological and pharmaceutical activities. The role of the thiazole is already exhibited by most epotilones used against multi-drug resistant tumor [5] and treatment of type 2 diabetes [6]. Organic non-linear optics (NLO) materials formed by a donor-acceptor pair in their molecular system exhibit noteworthy NLO characteristics [7]. Thiazoles with a push-pull system containing electron-withdrawing and electron donating groups have been studied in the past years in order to develop derivatives to be used as NLO materials [7, 8] . On the other hand, it is well known as an excellent ligand [9, 10] .

The title compound consists of a nitrothiazole and a benzyldiethylamine group connected by the C4–C5 double bond. It adopts the E configuration. The whole molecule is not planar. However, the nitrothiazole S1/O1/O2/N1/N2/(C1–C4) fragment is almost planar with maximum deviation of 0.029(2) Å for O1 from the least-squares plane. This plane and the plane of the phenyl moiety enclose an angle of 82.57(10)°. The double bond C4—C5 has a length of 1.372(3) Å. Distances C2—S1 and C3—S1 are 1.719(3) Å and 1.743(3) Å respectively, showing a partial double bond character for the bonds compared to 1.714(2) and 1.713(2) Å in 2-bromo-4-phenyl-1,3-thiozole [11]. The N2—C3 bond distance of 1.338(3)° is longer than that of the analoguous one (1.295(2) Å) indicating a degree of delocalisation due to the conjugation effect. Other bond lengths and angles are in normal ranges.
