Reaction Steps

1-[(2-Acetylthiomethyl-3-(acetylthio)propanoyl]-L-proline (1.2 g.) is dissolved in a mixture of water (12 ml.) and concentrated ammonia (12 ml.) under an atmosphere of argon. After twenty minutes, the mixture is acidified with concentrated hydrochloric acid. The crystalline precipitate 1-(2-mercaptomethyl-3-mercaptopropanoyl)-L-proline is filtered and dried, yield 0.63 g., m.p. 138°-140°.
