Versuchsvorschrift

A solution of the above crude (S)-2-methanesulfonyloxymethyl-1,4-benzodioxane, 1.05 g (2.71 mM) of N-(piperidin-4-ylmethyl)-5-thia-1,8b-diazaacenaphthylene-4-carboxamide dihydrochloride, and 1.20 ml (8.64 mM) of triethylamine in 30 ml of ethanol was refluxed for 3 days. The solvent was then distilled off under reduced pressure and the residue was purified by silica gel column chromatography (ethyl acetate to ethyl acetate-methanol=4/1 to 3/1) to provide the title compound and triethylamine hydrochloride as a mixture. This mixture was diluted with ethyl acetate and washed serially with aqueous solution of sodium hydrogen carbonate, water, and saturated aqueous solution of NaCl. The organic layer was dried over MgSO4 and the solvent was distilled off to provide the title compound.
