Abstract
Alkylene-, halo-, and aryl-substituted 2-methylthieno[2,3-d]thiazoles were obtained by the action of phosphorus pentasulfide on the corresponding 2-acetylamino-3-bromo- or 2-acetylamino-3-hydroxythiophenes in an organic solvent with heating. 2-Oximes of halo- and methyl-substituted isatins were converted by reduction and acylation into 2-hydroxy-3-acetylaminoin-doles, from which 2-methylindolo[3,2-d]-thiazoles were obtained by the action of phosphorous pentasulfide with heating in xylene.
