Reaktionsschritte

A solution of methyl 2-methyl-5-[4-(trifluoromethyl)phenyl]-3-furoate (intermediate 23, 0.27 g) in tetrahydrofuran (10 ml) stirred at 0° C. under a nitrogen atmosphere was treated with 1M lithium aluminium hydride in ether (1.0 ml). The reaction mixture was stirred at this temperature for 4 hours and then water (2 ml) and 2M aqueous sodium hydroxide (2 ml) added. The reaction mixture was further diluted with water; extracted with ethyl acetate and the organic solution extracted with water and dried with brine and over sodium sulfate and concentrated. The product isolated after evaporation of the solvent was further purified by Biotage™ chromatography using a mixture of petroleum ether:ethyl acetate (1:1) as eluent to give the title compound as a white solid.
