2-Amino-6-phenyl-7,8-dihydroindazolo[4,5-<i>d</i>]thiazoles
Abstract
Treatment of 4-oxo-1-phenyl-4,5,6,7-tetrahydroindazole and its 3-methyl, 6-phenyl, and 3-methyl-6 phenyl substituted derivatives with pyridinium bromide-perbromide and subsequent reaction of the 5-brorno derivatives obtained with thiourea gave 2-amino-6 phenyl-7,8-dihydroindazolo[4,5-d]thiazole and its corresponding substituted derivatives. The condensation of these products with 2-formyldimedone led to their 4,4-dimethyl-2,6-dioxocyclohexylidene derivatives.
