By treating /?-mercaptopropionic acid with aryl (aralkyl) isothiocyanates in weak alkaline medium, the authors have obtained the corresponding @-(N-aryl(aralky1)-thiocarbamoy1thio)-propionic acids which, heated 2 hours at 120°, yield the corresponding 3-aryl(aralkyl) -4-0x0-2-thiono-tetrahydrothiazi
