Reaction Steps

{4-[3-Bromo-5-(tert-butyl-dimethyl-silanyloxy)-benzylsulfanyl]-2-methylphenoxy}-acetic acid ethyl ester 7 g, 13.3 mmol) was dissolved in THF under an atmosphere of nitrogen. Tetrabutylammonium fluoride 1 N in THF (15 mL) was added, and the reaction mixture was stirred at 60° C. for 2 h. Saturated sodium carbonate and water were added together with ethyl acetate, and the organic phase was separated. The organic phase was washed with water, dried, and evaporated to dryness. Yield: 3.2 g. HPLC-MS: m/z: 435.4 (M+Na); Rt: 2.22 min.
