Synthesis of some heterocyclic derivatives from p-Morpholinocinchophen

Abstract EN

p-Morpholinocinchophen 1 was converted into its hydrazide 3 via the methylester 2.

Compound 3 was utilized as a starting material for the synthesis of 3-mercapto-4- (2-p-Morpholinocinchophenl-quionlin- 4-yl) -1, 2, 4-triazole 5, 1, 3, 4-oxadiazole 6, and 2-amino-4-(2-p-morpholinophenyl quinolin-4-yl) -1,3, 4-thiadiazole 7.
