Procedure

To a tetrahydrofuran (3 mL) solution of (4-cyclohexyloxy-phenyl)-acetohydroximoyl chloride (150 mg, 0.56 mmol) described in Manufacturing Example 79-1-4 and 3-ethynyl-pyridine-2,6-diamine (47.6 mg, 0.357 mmol) described in Manufacturing Example 13-1-3 was added triethylamine (195 μL, 1.4 mmol). This reaction mixture was stirred for 4 hours at room temperature. This mixture was partitioned into ethyl acetate and water. The organic layer was separated, washed with water, dried with 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 (83 mg, 41%).
