Reaction Steps

(1S,2S)-2-{4-[(R)-4-(4-Benzyloxy-phenoxy)-7-fluoro-indan-1-yloxy]-phenyl}-cyclopropanecarboxylic acid ethyl ester (Intermediate 6, 0.76 g, 1.3 mmol) is dissolved in 1:1 MeOH/ethyl acetate (20 mL) and hydrogenated at 2 Bar for 1 hour using 10% palladium on carbon as the catalyst. The mixture is filtered through CELITE filter aid and the solvent removed under vacuum the title compound. (Yield 0.60 g). LC (METHOD 6): tR=0.64 min; Mass spectrum (ES+): m/z=449 [M+H]+.
