Reaction Steps

To a mixture of (4-(5-methyl-furan-2-ylmethyl)-phenyl)-acetohydroximoyl chloride (11 mg, 0.043 mmol) described in Manufacturing Example 46-1-6 and tetrahydrofuran (1 mL) were added 3-ethynyl-pyridin-2,6-diamine (4.5 mg, 0.034 mmol) described in Manufacturing Example 13-1-3 and triethylamine (9.4 μL, 0.068 mmol), which was stirred for 3 hours at 40° C. Water was added thereto at the same temperature, which was extracted with ethyl acetate. The organic layer was washed with saturated aqueous sodium chloride, and was concentrated under a reduced pressure. The residue was purified by NH silica gel column chromatography (ethyl acetate: heptane=3:2) to obtain the title compound (9.2 mg, 76%).
