70% | With phosphorus pentachloride; triethylamine; In dichloromethane; water; | PREPARATION 4 Synthesis of <strong>[162651-07-2]2-bromo-4-trifluoromethyl-thiazole-5-carboxylic acid</strong> (cyano-thiophen-2-yl-methyl)-amide 1.2g of <strong>[162651-07-2]2-bromo-4-trifluoromethyl-thiazole-5-carboxylic acid</strong> and 1.0g of phosphorus pentachloride were added to 10ml of dichloromethane and then stirred under refluxing for one hour. After removing the solvent and phosphorus oxychloride under reduced pressure, the residue was dissolved again in 10ml of dichloromethane and 0.84g of amino-thiophen-2-yl-acetonitrile hydrochloride and 1.3ml of triethylamine were added thereto at 0oC. The reaction mixture was stirred for 2 hours at normal temperature. Water was added to the reaction mixture and the organic layer was separated. The separated organic layer was dried over anhydrous magnesium sulfate and then evaporated. The residue was then subjected to silica gel column chromatography to obtain 1.2g (Yield 70%) of the title compound. |
