Versuchsvorschrift

To a tetrahydrofuran (4 mL) solution of the (6-phenylsulfanyl-pyridin-3-yl)-acetohydroximoyl chloride (100 mg, 0.359 mmol) described in Manufacturing Example 97-1-4 and 3-ethynyl-pyridin-2,6-diamine (15 mg, 0.13 mmol) described in Manufacturing Example 13-1-3 was added triethylamine (55 μL, 0.40 mmol), which was stirred under nitrogen atmosphere for 1 hour at 50° C. Water was added to the reaction mixture, which was extracted with ethyl acetate. The organic layer was separated, washed with saturated aqueous sodium chloride, dried over anhydrous magnesium sulfate, and filtered. The filtrate was concentrated under a reduced pressure, and the residue was purified by NH silica gel column chromatography (ethyl acetate: methanol=10:1) to obtain the title compound (25 mg, 58%).
