Reaction Steps
To a tetrahydrofuran (3 mL) solution of (3-benzyloxy-phenyl)-acetohydroximoyl chloride (200 mg, 0.724 mmol) described in Manufacturing Example 61-1-4 and 3-ethynyl-pyridin-2,6-diamine (61.5 mg, 0.462 mmol) described in Manufacturing Example 13-1-3 was added triethylamine (252 μL, 1.81 mmol). This mixture was stirred for 4 hours at room temperature. This mixture was partitioned into water and ethyl acetate. The organic layer was separated, washed with water and saturated aqueous sodium chloride, dried over anhydrous magnesium sulfate, and filtered. The filtrate was concentrated under a reduced pressure. The residue was purified by NH silica gel column chromatography (heptane:ethyl acetate=1:1˜ethyl acetate) to obtain the title compound (138 mg, 51%).
