To a room temperature solution of 1-{4-[3-(2,6-dichloro-phenyl)-5-isopropyl-3H-[1,2,3]triazol-4-ylmethoxy]-2-methyl-phenyl}-ethanol (70 mg, 0.167 mmol) in toluene (2 mL) are added 3-mercapto-benzoic acid methyl ester (28 mg, 0.167 mmol) and tri-N-butylphosphine (62 μL, 0.251 mmol). The reaction mixture is cooled to 0° C. To the reaction mixture is added 1,1′-(azocarbonyl)-dipiperidine (63 mg, 0.251 mmol). The reaction mixture is warmed to room temperature and stirred overnight. The reaction mixture is concentrated and the residue is chromatographed (40 g SiO2, 0% to 30% EtOAc/Hexanes) to yield 3-(1-{4-[3-(2,6-Dichloro-phenyl)-5-isopropyl-3H-[1,2,3]triazol-4-ylmethoxy]-2-methyl-phenyl}-ethylsulfanyl)-benzoic acid methyl ester (62 mg, 65%).
