Procedure

From an aqueous solution of 2.8 parts of N-(2,6-dimethylphenyl)-N-(1-propyl-4-piperidinyl)-2-thiopheneacetamide dihydrochloride, the free base is liberated by alkalization with sodium hydrogen carbonate solution. The free base is extracted with 1,1'-oxybisethane. The extract is dried and evaporated. The oily residue is dissolved in 56 parts of hexane and after cooling to -10° C., the solid free base is precipitated. It is filtered off and dried, yielding 1.6 parts of N-(2,6-dimethylphenyl)-N-(1-propyl-4-piperidinyl)-2-thiopheneacetamide; mp. 62.5° C.
