Procedure

To flask containing (R) or (S)-methyl 2-(6-hydroxy-2,3-dihydro-1H-inden-1-yl)acetate (1.5) (0.0100 g, 0.0485 mmol) and cesium carbonate (0.0205 g, 0.0630 mmol) in DMF (1 mL) was added 2-(butyloxy)-4-(chloromethyl)-2′-fluoro-5′-(methyloxy)-1,1′-biphenyl (D) (0.0188 g, 0.0582 mmol). The reaction was then stirred overnight, diluted with water, and extracted with EtOAc. The combined organic layers were washed with brine, dried over anhydrous Na2SO4, filtered, concentrated, and then purified by silica gel chromatography (0 to 20% EtOAc/Hexane) to provide methyl ((1R)-6-(((2-(butyloxy)-2′-fluoro-5′-(methyloxy)-1,1′-biphenyl-4-yl)methyl)oxy)-2,3-dihydro-1H-inden-1-yl)acetate or methyl ((1S)-6-(((2-(butyloxy)-2′-fluoro-5′-(methyloxy)-1,1′-biphenyl-4-yl)methyl)oxy)-2,3-dihydro-1H-inden-1-yl)acetate 17.1.
