実験手順

To a tetrahydrofuran (5.00 mL) solution of (4-(4-fluoro-phenoxy)-phenyl)acetohydroximoyl chloride (290 mg, 1.04 mmol) described in Manufacturing Example 141-1-3 and 3-ethynyl-pyridine-2,6-diamine (40.0 mg, 0.300 mmol) described in Manufacturing Example 13-1-3 was added triethylamine (105 μL, 0.750 mmol) under nitrogen atmosphere at room temperature, which was stirred for 16 hours at room temperature. Water was added at room temperature to the reaction solution at room temperature, which was extracted with ethyl acetate. The organic layer was washed with 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=3:1→ethyl acetate) to obtain the title compound (38.1 mg, 33.7%).
