실험 절차

To a mixture of (4-(2-pyridin-2-yl-ethyl)-phenyl)-acetohydroximoyl chloride hydrochloride (780 mg, 2.51 mmol) described in Manufacturing Example 93-1-8 and dimethylformamide (10 mL) were added 3-ethynyl-pyridin-2,6-diamine (96 mg, 0.721 mmol) described in Manufacturing Example 13-1-3 and triethylamine (1.05 mL, 7.53 mmol), which was stirred for 3 hours at room temperature. Water and ethyl acetate were added to the reaction mixture, and the organic layer was separated. This organic layer was washed with water and saturated aqueous sodium chloride and dried over anhydrous magnesium sulfate, and the solvent was evaporated under a reduced pressure. The residue was purified by NH silica gel column chromatography (ethyl acetate: heptane=4:6 then ethyl acetate) to obtain the title compound (80 mg, 30%).
