Methyl 4-sulfanylbenzoate → 4-(1-{4-[3-(2,6-dichloro-phenyl)-5-isopropyl-3H-[1,2,3]triazol-4-ylmethoxy]-2-methyl-phenyl}-1-methyl-ethylsulfanyl)-benzoic acid methyl ester

Participants

Reaction Steps

To an ambient temperature solution of 2-{4-[3-(2,6-dichloro-phenyl)-5-isopropyl-3H-[1,2,3]triazol-4-ylmethoxy]-2-methyl-phenyl}-propan-2-ol (100 mg, 0.230 mmol) in DCE (1 mL) is added zinc iodide (37 mg, 0.115 mmol). The reaction is stirred at room temperature for 10 min. A solution of methyl 4-mercaptobenzoate (38 mg, 0.225 mmol) in DCE (1 mL) is added and the reaction is stirred overnight at room temperature. The reaction is concentrated under reduced pressure and the residue is chromatographed (SiO2 40 g, 0% to 30% EtOAC/Hexane to yield 4-(1-{4-[3-(2,6-dichloro-phenyl)-5-isopropyl-3H-[1,2,3]triazol-4-ylmethoxy]-2-methyl-phenyl}-1-methyl-ethylsulfanyl)-benzoic acid methyl ester (114 mg, 87%). 1H NMR (400 MHz, CDCl3) δ 7.81 (d, 2H, J=7.9 Hz), 7.52-7.39 (m, 3H), 7.22 (s, 1H), 7.16 (d, 2H, J=7.8 Hz), 7.11 (d, 1H, J=8.4 Hz), 6.63 (d, 1H, J=8.4 Hz), 4.90 (s, 2H), 3.90 (s, 3H), 3.23 (sept, 1H, J=6.6 Hz), 2.01 (s, 3H), 1.64 (s, 6H), 1.46 (d, 6H, J=6.6 Hz).
