Zusammenfassung:1335638 2-(4-Aminophenyl)-6-methylbenzothiazole CASSELLA FARBWERKE MAINKUR AG 9 Feb 1972 [10 Feb 1971] 6064/72 Heading C2C 2 - (4 - Aminophenyl) - 6 - methylylbenzothiazole (dehydrothio - p - toluidine) is prepared by reacting p-toluidine and sulphur in a ratio of 5-15 moles to 4 g-atoms above 280‹C and up to 550‹C at a pressure of at least 28 atm. absolute. The process may be operated continuously. The sulphur may first be dissolved in the toluidine at 130-160‹ C.
