Procedure

To a solution of isopropyl 2-[3-[[3-(3-fluorophenyl)-5-methoxy-phenyl]methylamino]-2,4-dimethyl-phenoxy]acetate (390 mg, 0.9 mmol, 1.0 eq) in CH2Cl2 (10 mL) at 0° C. was added dropwise ethyl mercaptan (321 mg, 5.2 mmol, 6.0 eq) and AlCl3 (690 mg, 5.2 mmol, 6.0 eq). The reaction mixture was stirred at room temperature for 1 h then poured into water and extracted with EtOAc. The organic extract was washed with water and brine, dried (Na2SO4), filtered and evaporated in vacuo. The residue obtained was purified by column chromatography (petroleum ether: EtOAc, 100:1 to 10:1) to give the title compound as a white solid (200 g, 53%).
