To flask containing methyl 3-(3-hydroxyphenyl)propanoate (available from Aagile Labs Division of Tyger Scientific) (0.25 g, 1.387 mmol) and cesium carbonate (0.5876 g, 1.804 mmol) in DMF (8 mL), was added 1.2 (0.3654 g, 1.665 mmol). The resulting mixture was then 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/hexane) to provide 1.3 (0.4575 g, 90.78% yield). MS ESI (pos.) m/e: 382.0 (M+H2O)+.
