Reaction Steps

To a tetrahydrofuran (5 mL) solution of 3-ethynyl-pyridin-2-ylamine (45 mg, 0.38 mmol) described in Manufacturing Example 1-2-3 and (4-(pyridin-2-yloxy)benzene)-acetohydroximoyl chloride (200 mg, 0.76 mmol) described in Manufacturing Example 209-1-4 was added triethylamine (139 mg, 1.4 mmol), which was stirred for 10 minutes at 60° C. The reaction solution was cooled to room temperature, NH silica gel was added, and the solvent was evaporated under a reduced pressure. The crude product that had adsorbed to the NH silica gel was purified by NH silica gel column chromatography (heptane:ethyl acetate=2:1, 1:1) to obtain the title compound (40 mg, 30%).
