Ethyl 1H-indole-2-carboxylate (500 mg, 2.64 mmol) was dissolved in anhydrous DMF (8 ml), followed by 1-(chloromethyl)-4-fluorobenzene (0.380 ml, 3.17 mmol) and the addition of solid potassium carbonate (730 mg, 5.29 mmol). This was stirred at 60° C. for 20 h, at which time the reaction was allowed to cool to room temperature. Precipitate formed upon the addition of water (40 mL), was isolated over a filter, and dried under high vacuum overnight to give 550 mg of the title compound as a white solid which was recrystallized from diethyl ether. Rf=0.55 (33% EtOAc/Hex.)
