Reactions of 2-amino-4-methyl-6-(2-pyridyl)- and 2-amino-4-methyl-6-phenyl- 7,8-dihydroindazolo[4,5-d]thiazoles with aldehydes

The reaction of 2-amino-4-methyl-6-(2-pyridyl)-7,8-dihydroindazolo[4,5-d] thiazole, obtained by treating 3-methyl-4-oxo-1-(2-pyridyl)-4,5,6,7- tetrahydroindazole with pyridinium bromide perbromide and then with thiourea, and 2-amino-4-methyl-6-phenyl-7,8-

2-Amino-6-phenyl-7,8-dihydroindazolo[4,5-d]thiazoles

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-bromo 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. 1996 Plenum Publishing Corporation.
