Reaction Steps

To a tetrahydrofuran (3 mL) solution of (4-phenoxymethyl-phenyl)-acetohydroximoyl chloride (150 mg, 0.545 mmol) described in Manufacturing Example 86-1-5 and 3-ethynyl-pyridin-2-ylamine (41 mg, 0.348 mmol) described in Manufacturing Example 1-2-3 was added triethylamine (104 μL, 0.747 mmol), which was stirred for 2 hours at 50° C. Water was added to the reaction solution at room temperature, which was then extracted with ethyl acetate. 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 (heptane:ethyl acetate=4:1-2:1) to obtain the title compound (39 mg, 20%).
