Synthesis of novel 5-substituted pyrazole derivatives as cannabinoid antagonists

A facile seven-step sequence was developed from 4′- bromopropiophenone, utilizing a Suzuki-type coupling with an alkene, to give several novel 5-substituted pyrazole derivatives in overall yields of 11-31%. They are potent CB1 antagonists and have binding
