A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 161797-99-5, Name is Ethyl 2-(4-hydroxyphenyl)-4-methylthiazole-5-carboxylate, molecular formula is C13H13NO3S. In a Patent£¬once mentioned of 161797-99-5, Formula: C13H13NO3S
The present invention provides a high-purity 2 – (3 – aldehyde – 4 – isobuoxy phenyl) – 4 – methyl thiazole – 5 – carboxylic acid ethyl ester, cyano phenol, sulfur on behalf of the acetamide as the starting material, merabilite acylation reaction 4 – hydroxy benzamide (II), the reaction product does not separation directly saisai zuo reaction, is separated to obtain 2 – (4 – hydroxy-phenyl) – 4 – methyl – 5 – thiazole carboxylic acid ethyl ester (III); of formula (III) acetate acylation reaction to the compound 2 – (3 – a aldehyde group – 4 – hydroxy-phenyl) – 4 – methyl – 5 – thiazole carboxylic acid ethyl ester (IV), the reaction product does not separation directly isobutyl reaction, formula (I) of 2 – (3 – aldehyde – 4 – isobuoxy phenyl) – 4 – methyl thiazole – 5 – carboxylic acid ethyl ester product, purity ? 99%, content ? 99%. The present invention production process is optimized, thereby greatly improving the quality of the products, and the yield is high. (by machine translation)
