3,3,-Diphenylcyclobutanamine is a psychostimulant drug which was originally prepared as an antidepressant in the late 1970s.[1] It appears to inhibit the reuptake of serotonin, norepinephrine, and dopamine, and may also induce their release as well.[1] The N-methyl and N,N-dimethyl analogues of the compound are also known and are more potent.[1] All three agents produce locomotor stimulation in animal studies, with the tertiary amine being the strongest.[1]

Synthesis

A number of methods were tried in order to construct the strained four-carbon ring. A synthesis of 3,3-diphenylcyclobutanone appeared in the literature.[2] The ketone was prepared in low yield by the reaction of diphenylketene with 2 equiv of diazomethane.[3] The latter synthesis, although low yielding, was used and the desired amines were prepared from 3,3-diphenylcyclobutanone.

Diphenylketene

Diphenylketene is produced by the elimination of hydrogen chloride from diphenylacetyl chloride in the presence of triethylamine.[4]
