Versuchsvorschrift

In a similar manner as described in step 1 of Example 3, the title compound was prepared from 6-{5-phenyl-1-[4-(trifluoromethyl)benzyl]-1H-pyrrol-2-yl}-2-naphthol (0.250 g, 0.564 mmol), prepared in step 2 of Example 8, methyl bromoacetate (0.103 g, 0.676 mmol) and cesium carbonate (0.920 g, 2.82 mmol). Purification on a Biotage FlashElute™ system with a KP-Sil Flash 40+M column (90 g Silica Gel, 60 Å) using 50% methylene chloride in hexane as the eluent gave methyl [(6-{5-phenyl-1-[4-(trifluoromethyl)benzyl]-1H-pyrrol-2-yl}-2-naphthyl)oxy]acetate as an off-white solid (0.271 g, 93%), mp 90–91° C.
