Participants

Reaction Steps

The titled compound was prepared according to the method described for 2-[3-(4-trifluoromethyl-benzyloxycarbonylmethyl)-phenylsulfanylmethyl]-benzoic acid 2,2,2-trichloro-ethyl ester above from 2-(4-carboxymethyl-phenylsulfanylmethyl)-benzoic acid 2,2,2-trichloro-ethyl ester (155 mg, 0.357 mmol), (4-trifluoromethyl-phenyl)-methanol (157 mg, 0.893 mmol), EDC×HCl (206 mg, 1.072 mmol), DMAP (4.4 mg, 0.036 mmol) and DCM (3 mL). The crude was submitted to flash chromatography using heptane and EtOAc (90/10) as eluent to yield the titled compound (74 mg, 35%) as an oil; 1H NMR (400 MHz, CDCl3): δ 3.64 (dd, 2H), 4.54 (s, 2H), 4.96 (s, 2H), 5.17 (s, 2H), 7.16 (d, 2H), 7.18-7.28 (m, 3H), 7.31-7.44 (m, 4H), 7.60 (d, 2H), 8.08 (d, 1H)); Mass spectrum: M−H+ 590.
