반응 단계

HOBt (0.0351 g, 0.260 mmol) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) (0.0460 g, 0.240 mmol) were added to a dimethylformamide (5.0 mL) solution of 6-cyano-2-phenyl-4-quinolinecarboxylic acid (0.0548 g, 0.200 mmol) described in Reference Example 22 and triethylamine (0.0223 g, 0.220 mmol), and the mixture was stirred at room temperature for 30 minutes. Commercially available 2-amino-5-(2-furyl)-1,3,4-oxadiazole (0.0332 g, 0.220 mmol) was added thereto, and the mixture was stirred at room temperature. The reaction solution was subjected to extraction with dichloromethane, washed with water and saturated saline, and dried over anhydrous sodium sulfate, and then, the solvent was distilled off. The obtained residue was fractionated by silica gel column chromatography, and the solvent was distilled off to obtain the title compound (0.001 g, 0.0024 mmol) as an amorphous substance.
