DIARYLBUTANOLAMINES

A method of preparing diarylhydroxybutylamine compounds of the formula I **(See formula)** or R2 and R3 taken together with the adjacent nitrogen atom to which they are attached, complete a heterocyclic ring selected from methyl or substituted dimethyl pyrrolidine, piperidine, morpholine or pyrrolidine, piperidine and morpholine; and its pharmaceutically acceptable, non-toxic salts, characterized by reacting a 1,2-epoxy 4,4-diarylbutane compound of formula II **(See formula)** where X is as defined above, with at least one equivalent of an amine of the formula **(See formula)** where R2 and R3 are as defined above, at a temperature of between 50º and 180ºC.
