| titleOfInvention | Production of n-substituted aminoethanethiol |
| abstract | PURPOSE:To enable economical production of the title compound by forming N-substituted 2,2-dialkylthiazolidine from a reagent corresponding to the subject compound and 2,2-dialkylthiazolidine and hydrolyzing the product in the presence of hydrohalogenic acid. CONSTITUTION:The reaction of a compound of formula R<1>-Y (R<1> is 1-20C alkyl; Y is COX, N=C=O, CH2X; X is halogen) with another compound of formula I (R<2>, R<3> are methyl, ethyl) is carried out, preferably at an equimolar ratio in the absence or presence of a solvent at 0 deg.C up to the boiling point of the solvent to give a compound of formula II (Z is CO, NHCO, CH2). Then, the product is hydrolyzed in the presence of a hydrohalogenic acid such as hydrochloric acid or hydrobromic acid under relatively mild conditions at 0 deg.C to the refluxing temperature to give the subject compound of formula III which is used as an intermediate of medicines, photographic reagents or cosmetics. |
