Reaction Steps

To a tetrahydrofuran (3 mL) solution of 3-ethynyl-pyridine-2,6-diamine (50 mg, 0.376 mmol) described in Manufacturing Example 13-1-3 and (4-benzylphenylsulfanyl-phenyl)acetohydroximoyl chloride (176 mg, 0.602 mmol) described in Manufacturing Example 205-1-5 was added triethylamine (131 μL, 0.94 mmol), which was stirred for 2 hours at room temperature. This mixture was partitioned into ethyl acetate and water. 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, and the residue was purified by NH silica gel column chromatography (ethyl acetate:heptane=1:1, then ethyl acetate) to obtain the title compound (80 mg, 55%).
