YieldReaction ConditionsOperation in experiment
With potassium hydroxide; In ethanol; EXAMPLE I 2-Ethyl 5-thiazolecarboxylic acid a solution of 26 gm of thiopropionamide in 100 cc of ethanol is mixed with a solution of 36.5 gm of <strong>[33142-21-1]ethyl 2-chloro-3-oxo-propionate</strong> in 50 cc of ethanol. The reaction mixture is left in contact overnight, then the alcohol is evaporated off. The residue is dissolved in ether, the ethereal phase is washed with an aqueous 20% sodium carbonate solution, then with water. The oil obtained is distilled and the fraction coming off at 80 C. to 90 C. under a pressure of 0.5 mm is recovered. This fraction is saponified with an alcoholic solution of potassium hydroxide, then acidified and recrystallized from toluene. 2-Ethyl-5-thiazolecarboxylic acid is obtained in the form of colorless crystals, soluble in ethanol and sodium hydroxide, insoluble in water, melting at 157 C. Analysis: C6 H7 NO2 S = 157.19: Calculated: C% 45.84: H% 4.49: N% 8.91: S% 20.40: Found: C% 46.1: H% 4.5: N% 8.7: S% 20.0.
