실험 절차

To a suspension of 5-chloro-1-ethyl-6,7-bis((4-methoxybenzyl)oxy)-4-oxo-1,4-dihydrocinnoline-3-carboxylic acid (3 g, 5.71 mmol) in tetrahydrofuran (THF) (25 mL) was added triethylamine (0.876 mL, 6.29 mmol), followed by isobutyl chloroformate (0.826 mL, 6.29 mmol). The reaction mixture was stirred at 0° C. for 30 min. 2-(Pyrrolidin-1-yl)ethanamine (0.979 g, 8.57 mmol) was added and the mixture was stirred at 0° C. for 30 min and warmed up to room temperature for 2 h. Solvent was removed and the residue was chromatographed to afford 5-chloro-1-ethyl-6,7-bis((4-methoxybenzyl)oxy)-4-oxo-N-(2-(pyrrolidin-1-yl)ethyl)-1,4-dihydrocinnoline-3-carboxamide (1.2 g, 1.932 mmol, 33.8% yield). LCMS: (M+H)+: 621.2
