YieldReaction ConditionsOperation in experiment
170 mg (75%) With sulfuric acid; In water; ethyl acetate; d) 4-Chloro-thiazole-5-carboxylic acid A solution of chomium(IV)oxide (149 mg, 1.49 mmol) in 300 mL deionized water was added dropwise to a stirred solution of <strong>[104146-17-0]4-chloro-thiazole-5-carbaldehyde</strong> (205 mg, 1.37 mmol) and in an ice bath (1.0 mL), followed by addition of sulfuric acid (8 drops). The ice bath was removed and the solution was stirred at ambient temperature for 30 min. Ethyl acetate (30 mL) was added to the solution and the solution was washed with deionized water (4*10 mL) and brine (2*10 mL). The ethyl acetate layer was extracted by a 10percent saturated sodium bicarbonate solution (2*20 mL). The aqueous extracts were acidified to pH 3 with a 10percent aqueous hydrochloric acid solution and were extracted with 1:1 dichloromethane:ethyl acetate solution (5*15 mL) and ethyl acetate (20 mL). The organic extracts were dried over sodium sulfate, decanted, and concentrated to yield 170 mg (75percent) of the title compound as a white solid. 1H NMR (Acetone-d6): 9.20 (s, 1H).
