Reaction Steps

To an ethanol solution (2 ml) of 7-[1-(pyridin-4-yl)piperidin-4-ylmethoxy]-1,2,3,4-tetrahydroisoquinoline-2-carbothioimidic acid methyl ester (100 mg) were added methylamine hydrochloride (20 mg) and sodium acetate (25 mg), and the mixture was stirred at 80° C. for 3 hours. After completion of the reaction, water was added and the mixture was washed with chloroform. Thereto was added aqueous sodium hydrogencarbonate solution and the mixture was washed with chloroform. To the aqueous layer was added 4N aqueous sodium hydroxide solution and the mixture was extracted with chloroform. The extract was washed successively with water and saturated brine. The organic layer was dried over anhydrous sodium sulfate and the solvent was evaporated and the obtained residue was treated with hydrogen chloride—ethanol solution and dried under reduced pressure to give the title compound (80 mg).
