Reaction Steps

To a tetrahydrofuran (5.00 mL) solution of (4-(2-fluoro-phenoxy)-phenyl)-acetohydroximoyl chloride (210 mg, 0.622 mmol) described in Manufacturing Example 83-1-3 and 3-ethynyl-pyridin-2,6-diamine (30.0 mg, 0.225 mmol) described in Manufacturing Example 13-1-3 was added triethylamine (94.1 μL, 0.675 mmol) 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 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=2:1) to obtain the title compound (41.7 mg, 49.2%).
