The free base of 2-(3-chloromethyl-phenoxymethyl)-quinoline hydrochloride (540 mg, 1.7 mmol, example 49) is prepard by partioning the material between ethyl ether and sodium bicarbonate and drying the organic phase with magnesium sulfate. This material is then dissolved with methyl salicylate (260 mg, 1.7 mmol) in DMF (10 mL) at 0° C. and sodium hydride (60%, 65 mg 1.7 mmol) is added. The reaction is brought to room temperature for 15 min. and is then heated at 60° C. for 6 h. The reaction is cooled and partioned between ethyl acetate and a saturated ammonium chloride solution. The organic phase is dried over magnesium sulfate, filtered, concentrated in vacuo and purified by column chromatography (silica, 50 to 80% ether in hexanes) to provide the title compound; MS (ESI) 400 (M+H)+.
