Versuchsvorschrift
To a solution of ethyl 2-cyano-5-phenyl-1,3-thiazole-4-carboxylate in THF was added a 1 M aqueous KOH solution, followed by stirring at room temperature for 12 hours. To the reaction mixture was added 1 M hydrochloric acid, and the solid precipitated was collected by filtration to obtain 2-carbamoyl-5-phenyl-1,3-thiazole-4-carboxylic acid as a pale yellow solid.
