To a tetrahydrofuran (3 mL) solution of (4-phenylamino-phenyl)-acetohydroximoyl chloride (150 mg, 0.576 mmol) described in Manufacturing Example 69-1-4 and 3-ethynyl-pyridin-2,6-diamine (48.9 mg, 0.367 mmol) described in Manufacturing Example 13-1-3 was added triethylamine (201 μL, 1.44 mmol). This mixture was stirred for 6.5 hours at room temperature. The mixture was partitioned into ethyl acetate and water. The organic layer was separated, washed with water and 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 (heptane: ethyl acetate=1:1˜ethyl acetate) to obtain the title compound (107 mg, 52%).
