Procedure

0.50 g (1.58 mmol) of 1-[tert-butyl(dimethyl)silyl]-3-isopropyl-1H-indol-5-yl-boronic acid (Example XII), 0.437 g (173 mmol) of tert-butyl-(4-hydroxy-3,5-dimethylphenoxy)acetate (Example IX), 0.286 g (1.58 mmol) of copper(II) acetate and 0.50 g of molecular sieve (4 Å, powdered) are suspended in 10 ml of dried dichloromethane. 0.64 ml (7.88 mmol) of pyridine and 1.10 ml (7.88 mmol) of triethylamine are added dropwise at room temperature. The batch is stirred overnight at room temperature. The batch is subsequently filtered through silica gel and washed with dichloromethane. The filtrate is concentrated and the residue is filtered through silica gel (dichloromethane). 0.525 g (62%) of tert-butyl-[4-({1-[tert-butyl-(dimethyl)silyl]-3-isopropyl-1H-indol-5-yl}oxy)-3,5-dimethylphenoxy]acetate is obtained.
