Procedure

A mixture of 3.8 parts of 2-(bromomethyl)-2,3-dihydro-1,4-benzodioxin, 6.3 parts of N-(4-piperidinylmethyl)-2-benzothiazolamine dihydrobromide, 10 parts of sodium carbonate, 0.1 parts of sodium iodide and 68 parts of N,N-dimethylformamide was stirred for 48 hours at 70° C. The reaction mixture was poured into water and the product was extracted with 4-methyl-2-pentanone. The extract was dried, filtered and evaporated. The oily residue was crystallized from acetonitrile, yielding 2.8 parts of N-[[1-[(2,3-dihydro-1,4-benzodioxin-2-yl)methyl]-4-piperidinyl]methyl]-2-benzothiazolamine; mp. 139.9° C. (compound 1).
