Brief introduction of 541-58-2

541-58-2, 541-58-2 2,4-Dimethylthiazole 10934, athiazole compound, is more and more widely used in various fields.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.541-58-2,2,4-Dimethylthiazole,as a common compound, the synthetic route is as follows.

General procedure: Typically, (hetero)aryl bromide (1.0 mmol), thiazole derivatives(2.0 mmol), Pd-PEPPSI complexes (0.01e0.5 mol%), base (2 mmol),acid additive (0.3 mmol), and 3mL of DMAc solvent were addedinto a parallel reactor. After heating at 130 C for 4 h, the resultingmixture was cooled to room temperature. Subsequently, 25mL ofwater and 20 mL of dichloromethane were added into the reactor,and the mixture was stirred for another several minutes, followedby extraction three times with dichloromethane (3 x 5 mL). Theorganic layer was then combined, dried over anhydrous sodiumsulfate, filtered, and evaporated under reduced pressure to give thecrude products. The crude products were then purified by silica-gelcolumn chromatography using petroleum etheredichloromethane(15/1) as the eluent. The obtained pure products were characterizedby 1H NMR and 13C NMR spectroscopy, and the spectra can be foundin the Supporting Information. And the isolated yields of productswere obtained based on the amounts of (hetero)aryl bromides.

541-58-2, 541-58-2 2,4-Dimethylthiazole 10934, athiazole compound, is more and more widely used in various fields.
