Benzothiazole derivatives
Benzothiazole derivatives R 0270The Synthesis of Aminobenzothiazoles from 2,3-Biaryl-5-anilino-∆ 3 -1,2,4-thiadiazolines. -2,3-Biaryl-5-anilino-∆ 3 -1,2,4-thiadiazolium bromides (I) undergo a thermally-promoted rearrangement forming 2-amidinobenzothiazoles (II). In some cases, the yield can be improved by adding a base. -(PAN*, K.; REITZ, A. B.; Synth.
