Procedure

(1S,2S)-2-{4-[(R)-7-Fluoro-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-indan-1-yloxy]-phenyl}-cyclopropanecarboxylic acid ethyl ester (Intermediate 4, 1.31 g, 2.8 mmol) is suspended in acetic acid (8 mL) and hydrogen peroxide solution (35% in water, 0.97 mL, 11.2 mmol) is added. The mixture is stirred for 1 hour then diluted with water and extracted with ethyl acetate. The organic extracts are washed with water and brine, dried over sodium sulfate and the solvent removed. The residue is dried under vacuum to give the title compound (Yield 0.95 g). LC (METHOD 6): tR=0.57 min; Mass spectrum (ES+): m/z=357 [M+H]+.
