Benzyloxyphenyl based synthesis of some novel N-acetylpyrazolines

Abstract

Substituted benzyloxyphenyl chalcones 1a-j on reaction with hydrazine hydrate 2 and glacial acetic acid 3 in 2-methoxyethanol as reaction medium gave novel substituted Nacetylpyrazolines 4a-j. Newly obtained N-acetylpyrazolines were characterized on the basis of FT-IR, 1 H-NMR, GC-MS, and elemental analysis.
