6-APDB
6-(2-Aminopropyl)-2,3-dihydrobenzofuran (6-APDB, 4-Desoxy-MDA, EMA-3) is a stimulant and entactogen drug of the phenethylamine and amphetamine classes.[1] It is an analogue of MDA where the heterocyclic 4-position oxygen from the 3,4-methylenedioxy ring has been replaced with a methylene bridge.[1] 6-APDB, along with 5-APDB, was first synthesized by David E. Nichols in the early 1990s while investigating non-neurotoxic MDMA analogues.[1] In animal studies, 6-APDB fully substitutes for MBDB and MMAI but not for amphetamine or LSD.It is banned by a blanket law on benzofurans and related compounds.
