With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.38205-60-6,1-(2,4-Dimethylthiazol-5-yl)ethanone,as a common compound, the synthetic route is as follows.
EXAMPLE 23 1-(2,4-Dimethyl-5-thiazolyl)-1-(3-pyridyl)ethanol 5-Acetyl-2,4-dimethylthiazole (2.5 g) in dry diethylether (10 ml) was added dropwise to a stirred solution of 3-lithiopyridine (from 3.5 g 3-bromopyridine) in diethylether at -70 C. After 3 hours the mixture was allowed to warm to room temperature. After a further 1 hour, aqueous sodium hydrogen carbonate was added and the organic layer was separated. The aqueous layer was extracted with diethylether. The material obtained from the combined organic layers was purified by flash chromatography to give the title compound, m.p. 107.5-109 C. 13 C Nmr (CDCl3) 16.3, 18.7, 32.7, 71.9, 123.1, 133.5, 137.9, 142.4, 146.9, 148.0 and 162.2 ppm.
38205-60-6, As the paragraph descriping shows that 38205-60-6 is playing an increasingly important role.
