[3-Bromo-5-(tert-butyl-dimethyl-silanyloxy)-phenyl]-methanol (6.4 g; 20.17 mmol) and (4-mercapto-2-methyl-phenoxy)-acetic acid ethyl ester (5.02 g; 22.19 mmol) were dissolved in THF (200 mL). Tributylphosphine (8.15 g; 40.34 mmol) and 1,1′-(azodicarbonyl)dipiperidine (10.17 g; 40.34 mmol) were added, and the reaction mixture was stirred for 14 h at room temperature. Water and ethyl acetate were added to the reaction mixture. The phases were separated. The organic phase was washed with water, dried, and evaporated. The crude product was purified by flash chromatography (heptane: dichloromethane (1:1)). Yield: 8 g; 80%. HPLC-MS: m/z: 527.0 (M+1); Rt: 3.10 min.
