Reaction Steps

To a solution of 4-(6-chloronaphthalene-2-sulfonyl)-1-(4-piperidylmethyl)-2-piperazinone hydrochloride (230 mg) in DMF (10 ml) were added S-methylisothiourea hemisulfate (348 mg), triethylamine (0.418 ml) and water (2 ml), and the mixture was stirred at 50° C. overnight. To the mixture was added S-methylisothiourea hemisulfate (348 mg) and triethylamine (0.418 ml), and the mixture was additionally stirred at 50° C. overnight. The solvent was concentrated and purified with CHP20 column chromatography (water:acetonitrile:1 N hydrochloric acid=70:30:1) to give colorless amorphous of the title compound (160 mg).
