Procedure

A solution of 4-[4-(5-methoxy-pyridin-2-yl)-phenoxymethyl]-5-methyl-furan-2-carboxylic acid methyl ester (52) (118 mg, 0.33 mmoles) in dry tetrahydrofuran (10 ml) was treated with potassium trimethylsilanoate (260 mg, 2.0 mmoles) and the mixture stirred under an argon atmosphere for 2 hours. After evaporation of the solvent the residue was purified by HPLC (gradient: 18% acetonitrile/82% water containing 0.1% trifluoroacetic acid to 98% acetonitrile/2% water at a rate of 1%/min) to afford compound 53 (60 mg) as a white solid.
