Procedure

To a mixture of (4-benzyloxy-phenyl)-acetohydroximoyl chloride (19 mg, 0.069 mmol) described in Manufacturing Example 1-1-3 and tetrahydrofuran (1 mL) were added 3-ethynyl-6-methoxymethyl-pyridin-2-ylamine (8.6 mg, 0.053 mmol) described in Manufacturing Example 26-1-7 and triethylamine (15 μL, 0.11 mmol) at room temperature, which was stirred for 5.5 hours at room temperature. Water was added at room temperature to the reaction mixture, which was then extracted with ethyl acetate-tetrahydrofuran (3:2). The organic layer was washed with saturated aqueous sodium chloride, and the solvent was evaporated under a reduced pressure. The residue was purified by NH silica gel column chromatography (ethyl acetate:heptane=2:3) to obtain the title compound (8.8 mg, 41%).
