Reaktionsschritte
To flask containing 26.1 (2.15 g, 7.14 mmol) and cesium carbonate (3.95 g, 12.1 mmol) in acetone (50 mL), was added iodomethane (0.667 mL, 10.7 mmol). The resulting mixture was stirred overnight. The reaction was diluted with water and extracted with EtOAc. The organic layers were washed with brine, dried over Na2SO4, filtered, concentrated, and then purified by combiflash (0 to 20% EtOAc/Hexanes) to provide methyl 26.2 (2.25 g, 99% yield).
