Procedure
(1S,2S)-2-{4-[(R)-7-Fluoro-4-(4-hydroxy-phenoxy)-indan-1-yloxy]-phenyl}-cyclopropanecarboxylic acid ethyl ester (Intermediate 7, 140 mg, 0.29 mmol), N-(2-hydroxyethyl)morpholine (42 mg, 0.32 mmol), and triphenylphosphine (84 mg, 0.32 mmol) are suspended in dry tetrahydrofuran (5 mL) and cooled to 0° C. Di-tert-butyl azodicarboxylate (74 mg, 0.32 mmol) is added, the mixture is stirred for 2 hours at 0° C. then 2 h at room temperature. The solvent is removed under vacuum and residue is purified by flash chromatography (0-20% ethyl acetate in cyclohexane) to give the title compound. (Yield 175 mg, 55% content). LC (METHOD 6): tR=0.57 min; Mass spectrum (ES+): m/z=562 [M+H]+.
