A process for preparing 1,3,4-oxadiazole derivatives By: Zhu, Dongxia; Lu, Hongfei; Zhang, Jing; Zhang, Jingping Assignee: Northeast Normal University, Peop. Rep. China The invention relates to a process for the prepn. of 1,3,4-oxadiazole derivs. I, wherein Ar is Ph, 2-OMe-Ph, 4-Me-Ph, or 2-thienyl. For instance, 2,5-bis(2-methoxyphenyl)-1,3,4-oxadiazole was prepd. by chlorination of 2-methoxybenzoic acid followed by amidation with NH2NH2 and heterocyclization in the presence of POCl3. ¼´£º Accession Number 2010:191008 CAN152:287388 CAPLUS |
