A mixture of 3.2 parts of 1-(3-chloropropoxy)-4-fluoro-2-(phenylmethoxy)benzene, 4.1 parts of N-(4-piperidinylmethyl)-2-benzothiazolamine dihydrobromide, 6 parts of sodium carbonate, 0.1 parts of sodium iodide and 67.5 parts of N,N-dimethylacetamide was stirred overnight at 75° C. Water was added and the product was extracted with 4-methyl-2-pentanone. The extract was dried, filtered and evaporated. The oily residue was crystallized from acetonitrile. The product was filtered off and dried, yielding 3.3 parts (65.2%) of N-[[1-[3-[4-fluoro-2-(phenylmethoxy)phenoxy]propyl]-4-piperidinyl]methyl]-2-benzothiazolamine; mp. 129.5° C. (compound 24).
