실험 절차

To (S)-2-Amino-4-[4-(4-benzoylamino-phenoxy)-6-methoxy-quinolin-7-yloxy]-butyric acid cyclopentyl ester (120 mg, 0.216 mmol) in DCM (2 ml) were added acetyl chloride (15 μL, 0.216 mmol) and triethylamine (33 μL, 0.238 mmol) at 0° C. The reaction mixture was stirred at 0° C. for 30 min. then at room temperature for 1 hour. The crude mixture was concentrated under vacuum and purified by preparative HPLC to provide the title compound as a mono-TFA salt (67 mg, 52% yield).
