Procedure

To a solution of methyl 6-(4-fluoro-5-isopropyl-2-methoxyphenyl)-3-oxoindane-5-carboxylate (45.9 mg, 0.129 mmol) in heptane (1 mL) and THF (1 mL) at −20° C. under N2, was added dropwise 3N MeMgCl in THF (86 uL, 0.258 mmol). The reaction mixture was stirred at −20° C. for 2 h. The mixture was quenched with sat. aq. NH4Cl and extracted with EtOAc (3×). The combined organic layers were washed with brine, dried (Na2SO4) and concentrated in vacuo. The residue was purified by flash chromatography on silica gel to give methyl 6-(4-fluoro-5-isopropyl-2-methoxyphenyl)-3-hydroxy-3-methylindane-5-carboxylate.
