ABSTRACT:

Some new 2-substituted benzoxazole-5-carbonyl-3, 5-dimethyl pyrazoles (3) and 2-substituted benzoxazol-5-carbonyl-3-methyl pyrazolones (4) were prepared from 2-substituted benzoxazol-5-carboxylic acid hydrazide (2) reaction with acetyl acetone and ethyl acetoacetate respectively. The new compounds were characterized by spectral data (IR and PMR).

KEYWORDS:
