Reaktionsschritte

To a reactivial containing ethyl[4-(1,1-dimethyl-2-{3-methyl-5-[4-(trifluoromethyl)phenyl]thien-2-yl}-2-oxoethyl)-2-methylphenoxy]acetate (intermediate 106, 36 mg) was added trifluoroacetic acid (0.22 ml) and triethylsilane (0.11 ml). The vial was then sealed and heated at 50° C. for 18 hours. The reaction was then allowed to cool to room and concentrated in vacuo. Purification by flash column chromatography eluting cyclohexane-1% EtOAc/cyclohexane yielded the title compound as a colourless oil.
