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.,541-58-2

General procedure: Aniline ligand (10.0mmol) and palladium dichloride (0.886g, 5.0mmol) were dissolved in 15mL of DMAc at room temperature. After the mixture was stirred for 0.5hat 80C, the methanol (50mL) was added and the precipitation was formed. The precipitate of palladium complexes was then dissolved in 5mL dichloromethane, then 20mL hexane was added. After crystallized from the mixture of ethanol and dichloromethylene, the palladium complex was obtained as light yellow crystals.

The synthetic route of 541-58-2 has been constantly updated, and we look forward to future research findings.

541-58-2, 2,4-Dimethylthiazole is a thiazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

541-58-2, The 2,4-dimethylthiazol-5-ylsulphonyl chloride used as a starting material is commercially available and is also described in J. Het. Chem., 1981, 18., 997. The material may also be prepared as follows :- o Chlorosulphonic acid (20 ml) was cooled to 15C in an ice/methanol bath.2,4-Dimethylthiazole (11.32 g) was added dropwise over 45 minutes, with the evolution of hydrogen chloride gas during the addition. The mixture so obtained was heated to 140-1500C for 16 hours. The resultant mixture was cooled to 110-120C and finely powdered phosphorus pentachloride (41.6 g) was added in small portions, with the evolution of further hydrogen 5 chloride gas during the addition. The mixture so obtained was heated to 12O0C for 1 hour. The mixture was cooled to ambient temperature and poured slowly into a vigorously stirred mixture of ice (200 g) and water (200 ml). The mixture so obtained was stirred for 30 minutes. The mixture was extracted with methylene chloride. The organic extract was dried over magnesium sulphate and purified by chromatography on silica using increasingly polar Q mixtures of isohexane and diethyl ether as eluent. There was thus obtained2,4-dimethylthiazol-5-ylsulphonyl chloride as a yellow oil (18.4 g); 1H NMR Spectrum: (CDCl3) 2.76 (3H, s), 2.77 (3H, s).

As the paragraph descriping shows that 541-58-2 is playing an increasingly important role.
