2-Diphenylmethylpyrrolidine (Desoxy-D2PM), also known as 2-benzhydrylpyrrolidine, is a stimulant psychoactive drug. It is the 4-dehydroxylated structural analogue of diphenylprolinol (D2PM), and is also similar in structure to desoxypipradrol (2-DPMP), both of which act as norepinephrine-dopamine reuptake inhibitors (NDRIs). Like D2PM and 2-DPMP, Desoxy-D2PM is sold as a designer drug, and has been used in the manufacture of legal highs. It has been marketed under the names A3A New Generation, A3A Methano, and Green Powder, and has been reported to cause hallucinations, violent behavior, dilated pupils, tachycardia, and high blood pressure.^[1][2][3]

Desoxy-D2PM has two enantiomers which are used industrially in their purified form as chiral derivatizing agents during chemical synthesis.^[4]

As of the 4th November 2010, the UK Home Office announced a ban on the importation of 2-Diphenylmethylpyrrolidine, following a recommendation from the ACMD.^[5] It was due to become a class B drug^[6] on the 28th March 2012,^[7] but the bill was scrapped, due to the presence of two steroids included in the bill that were later recommended to remain uncontrolled.^[8]
