Reaction Steps

3,4-dichloro-N-[6-(4-chloromethylphenoxy)-pyridin-3-yl]benzamide (0.61 g, 1.5 mmol) was dissolved in DMF (5 mL). To the resulting solution were added triethylamine (0.84 mL, 6.0 mmol) and thiomorpholine (0.15 mL, 1.5 mmol), and this solution was stirred overnight at 40° C. The resulting reaction solution was concentrated under reduced pressure. To the residue was added ethyl acetate and washed with a saturated sodium bicarbonate solution and brine. The organic layer was dried over anhydrous magnesium sulfate and evaporated. This residue was purified by silica gel column chromatography (chloroform:methanol=80:1). The obtained solid (0.56 g, 1.18 mmol) was dissolved in ethyl acetate (50 mL), and a solution of 4 N hydrogen chloride in ethyl acetate (0.295 mL, 1.18 mmol) was added, and this solution was stirred for 1 hour at room temperature. The precipitated crystals were collected by suction filtration, and recrystallized from methanol, to thereby yield 0.38 g of the title compound.
