To a solution of 10 parts of α,α-bis[2-(diisopropylamino)ethyl]-α-phenylacetamide in 350 parts by volume of ether is added dropwise with stirring 2 molar equivalents of hydrochloric acid in isopropyl alcohol. The mixture is stirred for about 2 hours when the resulting salt is separated by filtration to afford α,α-bis[2-(diisopropylamino)ethyl]-α-phenylacetamide dihydrochloride, melting at about 140° C.
