Heat to dissolve, add a catalyst, such as sulfuric acid or p-toluenesulfonic acid. Control the temperature at a suitable degree, about 100-150 ° C. After several hours of reaction, the crude product of 5-methylthiazole can be obtained. After distillation and recrystallization, the product is purified. < Br >
Another method is to use 2-bromo-3-pentanone and ammonium thiocyanate as the starting materials. First, the two are mixed in an organic solvent, such as acetonitrile. Stir at room temperature to obtain the initial intermediate. Then add basic substances, such as potassium carbonate, heat up to 60-80 ° C, and then react for a few times, the product gradually forms. After extraction, column chromatography, etc., pure 5-methylthiazole can be obtained.

More alpha-halogenone and thiourea are used as raw materials. Alpha-halogenated ketones, such as alpha-bromoacetone, are placed in a reaction vessel with thiourea in a certain ratio. Add an appropriate amount of alkali, such as sodium hydroxide, and react at an appropriate temperature to obtain 5-methylthiazole. After separation and purification, the product is purified.

This method is a classic way to synthesize 5-methylthiazole. Craftsmen choose the best according to the availability of raw materials, the cost, the purity of the product and many other factors.
