An industrial process for the preparation of 2-p-aminophenyl-6-methylbenzothiazole (562) (dehydrothiotoluidine) is based on the high temperature reaction of sulfur with p-toluidine (561 Scheme 297). A similar process involves the simultaneous action of sulfur and carbon disulfide on a primary arylamine. BenzothiazoIe-2-thione (564) (2-mercaptobenzothiazoIe) is synthesized industrially by reaction of aniline (563) with sulfur and carbon disulfide (Scheme 298). In this synthesis, sulfur plays the role of a dehydrogenating reagent and may be replaced by nitrobenzene.

Kim and coworkers have reported a synthetic route to diverse heterocyclic compounds through the nucleophihc addition of P-amino carbonyl compounds 79 to 3-halo-4-methoxybenzynes 78 (Scheme 12.25) [51]. The benzyne intermediate 78 was generated from 5-(3-halo-4-methoxyphenyl)thianthrenium perchlorates 77 upon treatment with lithium diisopropylamide (LDA) in THF at reflux. P-Amino carbonyl compounds, such as P-amino ketones, esters, amides and aldehydes, all react smoothly with benzyne 78 under the reported reaction conditions. Moreover, bis(2-aminophenyl) disulfide, 2-aminophenyl benzenesulfonate...
