  An efficient aromatization of 1,3,5-trisubstituted 2-pyrazolines to their corresponding pyrazoles by NBS was carried out under microwave irradiation and solvent-free conditions in moderate yields. It has also been observed that, by activating the NBS reagent on silica gel as a support the reaction times can be dramatically reduced and good yields are obtained.
