Versuchsvorschrift

To a solution of 4-fluoro-3-methoxybenzoic acid (0.082 g) in THF (1 ml) was added carbonyldiimidazole (0.078 g) and the resulting solution stirred at room temperature for 10 minutes before addition of the product of Step e (0.15 g) in THF (1.5 ml). The mixture was stirred for 2 hours and the solvent removed by evaporation to yield a colourless gum. Purification by reverse phase HPLC (with a gradient eluent system 25% MeCN/NH4OAc(aq) (0.1%) to 95% MeCN//NH4OAc(aq) (0.1%)) gave the title compound (0.011 g).
