실험 절차

6 ml of 2N NaOH are added to a solution of 0.42 g of ethyl 4,5,6,7-tetrahydrobenzothiazole-5-carboxylate [952203-30-8] and 24 ml of MeOH at room temperature. After 6 hours, the reaction mixture is evaporated. The residue is acidified with 4N HCl, diluted with water and extracted with ethyl acetate (2×)—the combined organic phases are dried with sodium sulphate and evaporated. The crude title compound is obtained from the residue.
