| | 2-PHENYL-1,3-THIAZOLE-4-CARBOXYLIC ACID Usage And Synthesis |
| Synthesis | 2-PHENYL-1,3-THIAZOLE-4-CARBOXYLIC ACID was synthesized from benzaldehyde via a one-pot reaction with methyl 3-(dimethylamino)-2-isocyanoacrylate. This method features mild reaction conditions, high purity, simple operation, and no catalyst required, and can assemble various functional groups into the molecule. 
Synthetic reaction formula of 2-phenyl-1,3-thiazolyl-4-carboxylic acid Experimental procedure: Synthesis of methyl 2-phenyl-1,3-thiazolyl-4-carboxylate Benzaldehyde, methyl 3-(dimethylamino)-2-isocyanoacrylate, and anhydrous methanol were added sequentially to a reaction flask. Anhydrous magnesium sulfate was added with stirring, and the mixture was cooled in an ice-water bath and reacted at 0℃ for 2 h. The temperature was then raised to 30℃ and reacted for 16 h. The solvent was evaporated under vacuum to obtain methyl 2-phenyl-1,3-thiazolyl-4-carboxylate. Synthesis of 2-PHENYL-1,3-THIAZOLE-4-CARBOXYLIC ACID: Methyl 2-phenyl-1,3-thiazol-4-carboxylate, aqueous lithium hydroxide solution, and methanol were added sequentially to a reaction flask, and the mixture was reacted at 30°C for 6 h with stirring. The solvent was removed under vacuum, the pH was adjusted to 3-5 with dilute hydrochloric acid, and the mixture was extracted with dichloromethane (2 × 50 mL). The extracts were combined, concentrated, and purified by silica gel column chromatography [eluent: V(dichloromethane):V(methanol) = 15:1] to obtain 2-PHENYL-1,3-THIAZOLE-4-CARBOXYLIC ACID. | | Uses | 2-Phenylon-1,3-Thiazol-4-carboxylic acid, as a derivative of thiazol-4-carboxylic acid, is widely used in the pharmaceutical and chemical industries. Thiazol-4-carboxylic acid is a key intermediate in the synthesis of thiabendazole, one of the earliest benzimidazole drugs developed. It was successfully developed by Merck & Co., Inc. in 1968. Thiabendazole has a wide range of applications, mainly as an antiparasitic drug, bactericide, and preservative. | | Chemical Properties | Light yellow powder |
