Or start with the construction of the thiazole ring. Based on compounds containing nitrogen, sulfur and carbonyl groups, the thiazole ring is formed by cyclization reaction. Under specific conditions, such as heating and catalysis with appropriate catalysts, the reaction molecules interact with each other to form a ring, and methoxy groups are introduced at the same time. The catalysts involved may be metal salts, such as copper salts, zinc salts, etc., which can promote the formation and rearrangement of chemical bonds and guide the reaction towards the direction of generating 2-methoxythiazole.

After the reaction is completed, the product or mixed in the reaction system must be separated and purified to obtain pure 2-methoxythiazole. The commonly used methods include distillation, which separates the product according to its boiling point characteristics, and column chromatography, which uses the difference between the stationary phase and the mobile phase to separate the product from the impurities and ultimately obtain a pure 2-methoxythiazole.
