Procedure

A solution of 4-{[4-(5-methoxy-pyridin-2-yl)-phenylamino]-methyl}-5-methyl-furan-2-carboxylic acid methyl ester trifluoroacetic acid salt (165) (38 mg, 0.082 mmoles) in tetrahydrofuran (4 ml) was treated with potassium trimethylsilanoate (63 mg, 0.049 mmoles) and the mixture stirred at room temperature for 16 hours. The mixture was evaporated to dryness and pumped under high vacuum to remove silanol volatiles. The residue was purified by HPLC to afford a residue, which was dissolved in 1M aqueous hydrochloric acid. The solution was evaporated to give compound 166 as a solid (30 mg). LC/MS System A; Rt=2.22 mins, m/z (ES+)=339 (M+H for C19H18N2O4) and m/z (ES−)=337 (M−H for C26H25N3O5S).
