実験手順
To a solution of ethyl 2-mercapto-4-thiazole acetate (203 mg) in 1,4-dioxane (1.0 ml) was added 1N-sodium hydroxide solution (2.0 ml) at room temperature. After stirring at the same temperature for 2 hours, the solution was poured into a mixture of ethyl acetate and water, and adjusted to pH 8.0 with 1N-hydrochloric acid. The separated aqueous solution was adjusted to pH 3.0 with 1N-hydrochloric acid and extracted with ethyl acetate. The organic layer was washed with saturated sodium chloride solution, dried over magnesium sulfate and evaporated under reduced pressure to give 2-mercapto-4-thiazole acetic acid (120 mg).
