Reaktionsschritte

A suspension of 1-(3-((6-chloro-2-naphthyl)sulfonyl)propionyl)piperazine (2.5 g) obtained in Example 3a), N-((2Z)-4-chloromethyl-3-methyl-1,3-thiazol-2(3H)-ylidene)-N-methylamine hydrochloride (2.2 g) and potassium carbonate (2.4 g) in DMF (50 mL) was mixed at 65° C. for 3 hours. The solvent was distilled off under reduced pressure, the residue was diluted with an aqueous potassium carbonate solution, and extracted with chloroform. The extract was dried over anhydrous magnesium sulfate, and then concentrated under reduced pressure. The product, which was obtained by the purification of the residue with a basic silica gel column, was dissolved in ethyl acetate. A solution of hydrogen chloride in ether was added thereto, and the mixture was concentrated and dried to give the title compound (2.4 g) as a colorless powder.
