Unusual behaviour of 4,5-dichloro-1,2,3-dithiazolium chloride (Appel's salt) with 5-aminopyrazoles: a synthetic method of 1H-pyrazolo[3,4-d]thiazoles

Abstract

1H-Pyrazolo[3,4-d]thiazole-5-carbonitriles 9 are obtained by treating 4-unsubstituted 5-aminopyrazoles with Appel's salt at room temperature in the presence of 2,6-dimethylpyridine.
