1-[2-Hydroxy-4-(quinolin-2-ylmethoxy)-phenyl]-ethanone (185 mg, 0.63 mmol, example 58) is dissolved in 2:1 DMF/acetonitrile (6 mL). Ethyl (2-bromomethyl-6-methyl-phenoxy)-acetate (272 mg, 0.95 mmol, example 43b) and K2CO3 (177 mg, 1.26 mmol) are added and the contents are heated to 50° C. for 2 days. The reaction is cooled to r.t. and the volume reduced under a nitrogen stream at 40° C. The contents are partitioned between ethyl acetate (50 mL) and water (50 mL). The aqueous layer is further extracted with ethyl acetate (2×50 mL). The organic fractions are combined and washed with brine (3×75 mL), dried over MgSO4 and concentrated. The crude material is dissolved in 1:1 dichloromethane/methanol, preadsorbed onto silica gel, and purified by flash chromatography (silica, 20% ethyl acetate in hexanes) to give the title compound. MS (ion spray) 500 (M+H)+.
