Abstract:
Schiff base derivatives of 1H-3-methyl-4-ethoxycarbonyl-5-amino-pyrazole (1) and the substituted benzaldehydes were condensed under acid catalysis with azeotropic removal of the water formed in the reaction. The obtained compounds were characterized by melting point, TLC, IR and UV-VIS spectroscopy.
Keywords:
Schiff base, 1H-3-methyl-4-ethoxycarbonyl-5-amino-pyrazole, azeotropic distillation
