Abstract
3-Methyl-4-aryl-1-phenyl-1H -pyrazolo[3,4-d]-pyrimidine-6-thiols(
11)were synthesised by the raction of thiourea with 3-methyl-'
-1-phenyl-4-arylidene-2-pyrazolin-5-ones(1) in ethanolic solution of
potassium hydroxide. The mechanism of this reaction is discussed
and further transformation of the products with different reagents
(S-methylation, substitution of SR-group by arylamines, hydrazine,
and azide) was carried out.
