Procedure

{3-[2-tert-Butylsulfanylmethyl-4-(2,2-dimethyl-propionylamino)-phenoxy]-4-methoxy-phenyl}-acetic acid (0.953 g, 2.07 mmol) in CH2Cl2 was cooled to 0° C. Boron tribromide (1M in CH2Cl2; 6.21 mL, 6.21 mmol) was added, and the reaction was stirred at room temperature for 2 hours. The reaction was quenched, and after aqueous work-up, the crude material was purified by preparative HPLC to give the title compound.
