Versuchsvorschrift

To a solution of 315 mg of the ester from Step B in 3 mL of DMF were added 225 mg of milled K2CO3 and 272 mg of 2-(bromomethyl)quinoline. The mixture was stirred at R.T. for 18 h, poured into 25% aq. NH4OAc, and extracted with ethyl acetate. The organic extract was dried over Na2SO4 and evaporated to dryness to give an oil which was chromatographed on flash silica gel using ethyl acetate:hexane (30:70) as eluant to give the title compound as a foam.
