A mixture of 6.7 parts of 1-[(2,3-dihydro-1,4-benzodioxin-2-yl)methyl]-4-piperidinemethanamine dihydrobromide, 3.26 parts of 2-(methylsulfonyl)thiazolo[4.5-c]pyridine, 4.25 parts of sodium carbonate and 18 parts of N,N-dimethylacetamide was stirred for 2 hours at 150° C. The reaction mixture was poured into ice water. The product was extracted with 4-methyl-2-pentanone. The extract was dried, filtered and evaporated. The residue was purified by column chromatography over silica gel using a mixture of trichloromethane and methanol (97:3 by volume) as eluent. The pure fractions were collected and the eluent was evaporated. The residue was crystallized from 1,1'-oxybisethane. The product was filtered off and dried, yielding 1.15 parts (20%) of N-[[1-[(2,3-dihydro-1,4-benzodioxin-2-yl)methyl]-4-piperidinyl]methyl]thiazolo[4,5-c]pyridin-2-amine; mp. 147.1° C. (compound 58).
