반응 단계
11.4 g of cysteamine hydrochloride and 10.1 g of triethylamine were dissolved in 100 ml of ethanol, to which was added 10.2 g of 2-keto-butyric acid. The mixture was refluxed for 30 minutes, cooled and filtered thereby giving 10.6 g (yield 65.7%) of 2-ethyl-thiazolidine-2-carboxylic acid with a melting point of 235°-238° C. (decomposed).
