To an anhydrous tetrahydrofuran (5 mL) solution of 3-ethynyl-pyridin-2-ylamine (39 mg, 0.33 mmol) described in Manufacturing Example 1-2-3 was added (4-(2-pyridin-2-yl-ethyl)-phenyl)-acetohydroximoyl chloride hydrochloride (310 mg, 1.0 mmol) described in Manufacturing Example 93-1-8 under nitrogen atmosphere at room temperature. Triethylamine (0.42 mL, 3.0 mmol) was then added dropwise, and stirred for 2 hours at 60° C. The reaction mixture was partitioned into water and ethyl acetate at room temperature. The organic layer was washed with water and saturated aqueous sodium chloride and dried over anhydrous magnesium sulfate, and the solvent was evaporated under a reduced pressure. The residue was purified by NH silica gel column chromatography (ethyl acetate:heptane=3:7 then 4:6), and the resulting crude product was further purified by silica gel thin-layer chromatography (ethyl acetate) to obtain the title compound (21.2 mg, 18%).
