A solution of 480 mg of 1-methyl-2-{2-[2-(2-phenylethyl)phenoxy]ethyl}pyrrolidine [prepared as described in step (a) above] in a suitable amount of ethyl acetate was treated with 0.5 ml of a 4N solution of hydrogen chloride in dioxane, and the resulting mixture was then concentrated by distillation under reduced pressure. The resulting oily residue was dissolved in 10 ml ethyl acetate, and the solution thus obtained was allowed to stand at room temperature. The crystals which precipitated were collected by filtration, to give 130 mg (yield 24%) of the title compound as colorless needles, melting at 154°-156° C.
