The "two dogs" or "dopeboy" clandestine method, starting with helional as a precursor. First, an oxime is created using hydoxylamine. Then, a Beckmann rearrangement is performed with nickel acetate to form the amide. Then a Hofmann rearrangement is done to form the freebase amine of MDA. Then it is purified with an acid base extraction.
Results suggested that dogs with a particular genetic variant of the oxytocin receptor responded more strongly to the oxytocin spray, which made them more likely to seek help from their owners.
