38205-66-2, 1-(4-Thiazolyl)ethanone is a thiazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
In a 50 ml round-bottomed flask, 8 ml of anhydrous diethyl ether and 0.311 ml (2.2 mmol) of diisopropylamine were added, the solution was cooled to -60C, and then 2.5 N of n-hexane solution of BuLi (2.2 mmol) was added dropwise to the upper reaction system.The reaction system was warmed to 0C and stirred for 15 minutes. Then, drosalactone (500 mg, 2.0 mmol) was added dropwise at -60C.The ether solution was stirred for a further 40 min and then a solution of 4-acetylthiazole (254.3.4 mg, 2.0 mmol) in diethyl ether was added dropwise to the upper reaction system.The reaction system was stirred at this temperature for 50 min. The reaction was quenched with water. The organic layer was separated, washed with saturated sodium chloride, dried over anhydrous sodium sulfate, filtered, and the solvent was distilled off under reduced pressure. The residue was separated by silica gel column chromatography to give CYL-2- QX-3C, yield 55.0%., 38205-66-2
The synthetic route of 38205-66-2 has been constantly updated, and we look forward to future research findings.
