Procedure
In the manner described in example 1 starting from 49 parts of meta-phenoxyaniline and 83.3 parts of bis-(β-bromoethyl)amine dihydrobromide there was obtained a clear solution. After evaporation of the solvent in vacuo, the residue was treated with 700 part of water, rendered alkaline with 60 parts of concentrated NaOH and extracted twice with 200 parts of ether. Th solution was dried. Upon distillation, there were obtained 26 parts of 1-(3-phenoxyphenyl)-piperazine, B.P./0.5 mm Hg: 180°-190° C.
