title: Synthesis of the pyrazole isostere of valdecoxib.
abstract: 4-(5-methyl-3-phenyl-1H-pyrazole-4-yl)-benzenesulfonamide, the pyrazole isostere of valdecoxib was synthesised. The title compound was prepared by a six-step procedure starting from commercially available deoxybenzoin 1. The pyrazole isostere 13 showed slight anti-inflammatory and analgesic activities.
