실험 절차

(1S,2S)-2-[4-((R)-7-Fluoro-4-hydroxy-indan-1-yloxy)-phenyl]-cyclopropanecarboxylic acid ethyl ester (Intermediate 5, 0.6 g, 1.7 mmol), 4-benzyloxyphenylboronic acid (1.53 g, 6.7 mmol), copper (II) acetate (306 mg, 1.7 mmol), triethylamine (1.83 mL, 13.1 mmol), 4-dimethylaminopyridine (21 mg, 0.17 mmol) and 4 Å molecular sieves (3 g) are suspended in dichloromethane and stirred under an oxygen atmosphere over a weekend. The mixture is filtered through a plug of CELITE filter aid, washing the filter cake with dichloromethane. The organic phases are washed with 1 M aqueous HCl solution, dried and the solvent removed. The residue is purified by flash chromatography (0-40% ethyl acetate in cyclohexane) to give the title compound (Yield 0.76 g). LC (METHOD 6): tR=1.04 min; Mass spectrum (ES+): m/z=539 [M+H]+.
