실험 절차

A mixture of 21 (2.4 g, 8.89 mmol), K2CO3 (4.97 g, 35.96 mmol) and 2-fluoro-4-nitrophenol (1.55 g, 9.89 mmol) were heated at 150° C. in diphenyl ether (40 mL) for 2 days. The mixture was purified by column chromatography (eluents EtOAc-hexane 5:95, 2:8, then MeOH-EtOAc 2:98, 5:95) to give the title compound 22 as a yellow solid (3.23 g, 93% yield). MS (m/z): 388.2 (M+H).
