5-(2-Aminopropyl)-23-dihydrobenzofuran (5-APDB 3-Desoxy-MDA EMA-4) is a putative entactogen drug of the phenethylamine and amphetamine classes. It is an analogue of MDA where the heterocyclic 3-position oxygen from the 34-methylenedioxy ring has been replaced by a methylene bridge. 6-APDB is an analogue of 5-APDB where the 4-position oxygen has been replaced by a methylene bridge instead. 5-APDB was developed by a team led by David E.
