Reaction Steps

To a solution of 6-hydroxy-1,3,3-trimethyl-1,3-dihydro-indol-2-one (396 mg, 2.07 mmol) in DMF (7.6 mL) is added 6-(3-Bromomethyl-phenyl)-hexanoic acid methyl ester (682 mg, 2.28 mmol) and potassium carbonate (315 mg, 2.28 mmol). The resulting mixture is heated to 60° C., stirred for 2 hrs. then cooled to room temp and diluted with EtOAc. The organic layer is washed with water, brine, dried over MgSO4 and concentrated. The residue is purified by flash chromatography (eluting with 30% ethyl acetate/hexanes) to give 352 mg of title compound. MS (ESI) 410 (M+H)+.
