Acid Catalyzed Synthesis of substituted-n-((1, 3-diphenyl-1h-pyrazol-4-yl) methyl) benzenamine

A new derivative synthesis of Substituted-N-((1, 3-diphenyl-1h-pyrazol-4-yl) methyl) benzenamine has attempted by using commonly available key starting materials Acetophenone (1) and substituted phenyl hydrazine in presence of sulfuric acid catalyst and alcohol solvent to afford potential antiviral active analogues. The synthesis proceeds through Vilsmeier-Haack reaction followed by reductive amination by using sodium borohydride.
