C(α),N-Tbiosemlcarbazones or C(α),N-semicarbazones were polylithiated with excess lithium diisopropylamide, and the resulting cyclized intermediates were condensed with aromatic esters to afford N-(1H-pyrazol-3-yl)arylamides. The polylithiated intermediates were also quenched with aqueous acid to give 5-substituted, 1H-pyrazol-3-amines.
