Procedure

4-Chloro-6-cyano-7-(2-methoxyethoxy)quinoline (187 mg, 0.71 mmol), (prepared as described for the starting material in Example 1 but with an aqueous sodium hydrogen carbonate work up), was added to a solution of 5-benzyloxy-2-fluoro-4-methylphenol (248 mg, 1 mmol), (prepared as described for the starting material in Example 3), and potassium t-butoxide (120 mg, 1 mmol) in DMSO (5 ml) and the mixture then heated at 160° C. for 1.5 hours. The mixture was diluted with water and extracted with ethyl acetate. The organic layer was separated, washed with brine, dried (MgSO4) and the solvent removed by evaporation. The residue was purified by column chromatography eluting with methylene chloride/ethyl acetate (55/45) followed by preparative reverse-phase HPLC eluting with aqueous ammonium carbonate (2 g/1, adjusted to pH7 with carbon dioxide) and methanol (20/80) to give 4-(5-benzyloxy-2-fluoro-4-methylphenoxy)-6-cyano-7-(2-methoxyethoxy)quinoline (204 mg, 63%).
