Procedure

To a tetrahydrofuran (3 mL) solution of (4-benzylamino-phenyl)-acetohydroximoyl chloride (150 mg, 0.546 mmol) described in Manufacturing Example 68-1-4 and 3-ethynyl-pyridin-2,6-diamine (46.4 mg, 0.348 mmol) described in Manufacturing Example 13-1-3 was added triethylamine (190 μL, 1.37 mmol). The mixture was stirred for 6.5 hours at room temperature. This 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 (17 mg, 8.4%).
