Abstract
3-Cyclopropyl-5-(4-substituted)-1-phenyl-4,5-dihydro-1H-pyrazoles derived from corresponding chalcones were synthesized and evaluated for their biological activities. A convenient synthesis of a library of these compounds in 1-butyl-3-methylimidazolium hexafluorophosphate-water biphasic system at ambient temperature has been accomplished. The ionic liquid, [bmim][PF6] and water which are immiscible, has been easily recycled and reused after separation of the products without any noticeable diminution in its activity.
