Procedure

To a tetrahydrofuran (3 mL) solution of 3-ethynyl-pyridine-2,6-diamine (43.2 mg, 0.325 mmol) described in Manufacturing Example 13-1-3 and (2-fluoro-4-(pyridin-2-yloxymethyl)-phenyl)acetohydroximoyl chloride (150 mg, 0.509 mmol) described in Manufacturing Example 204-1-8 was added triethylamine (97.2 μL, 0.697 mmol), which was stirred for 2 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 (ethyl acetate:heptane=1:1, then ethyl acetate) to obtain the title compound (73 mg, 37%).
