Source of material
The solution of 2-oxo-2-phenylacetaldehyde (134 mg, 1 mmol) and tert-butyl-(2-amino-4,5-dimethylphenyl)carbamate (236 mg, 1 mmol) in isopropyl alcohol was added in a 20 mL microwave vial, then the 8-bromo-2-phenylimidazo[1,2-α]pyridine (273 mg, 1 mmol) was added. The reaction solution was stirred at 60 °C for 3 h, then evaporated. The residue was dissolved in 5% trifluoroacetic acid (TFA)/dichloroethane (DCE), which was sealed and heated under microwave irradiation at 60 °C for 10 min. The reaction mixture was washed with water and brine, and extracted with ethyl acetate. The organic solution was dried and concentrated, and purified by column chromatography over silica gel eluting with a gradient of ethyl acetate (EA)/hexane (Hex) (0–20%) to afford the yellow solid. Yield, 303 mg, 60%. The title compound (200 mg, 0.39 mmol) was dissolved in 20% EA/Hex, and the solvent slowly evaporated at room temperature. After 1 week, yellow crystals were obtained.
Experimental details
All of the hydrogen atoms were placed in the calculated positions and all the non-hydrogen atoms were refined anisotropically.
Discussion
Imidazo[1,2-α]pyridine and quinoxaline are important nitrogen-containing aromatic heterocyclic compounds, which posess a p-conjugated system, as well as desirable electronic and charge-transport properties [4]. These characteristics result in the extensive potential application in chemistry [5], materials chemistry and medicinal chemistry [6].
The asymmetric unit of the title compound contains two molecules. The bond lengths and angles in both crystallographically independent molecules are in the normal ranges. In conclusion, we have developed a facile microwave-assisted process for the synthesis of an imidazo[1,2-α]pyridine-quinoxaline compound using a one-pot procedure. This facile procedure can be readily used to synthesize a diverse range of compounds for high throughput screening in medicinal chemistry.
