Description
Summary:A simple approach to synthesize 4b,5,6,9-tetrahydro-7<i>H</i>-dibenzo[<i>c</i>,<i>e</i>]pyrrolo[1,2-<i>a</i>]azepin- 7-one has been developed, based on a three-step transformation of 2-(2-bromophenyl)cyclopropane-1,1-diester. The key stage in this method is an intramolecular cross-coupling of 1-(2-bromobenzyl)-5-(2-bromophenyl)pyrrolidin-2-one under continuous flow conditions in an H-Сube-Pro using commercially available supported Pd catalysts.
