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-(3-carboxymethyl-phenylsulfanylmethyl)-benzoic acid 2,2,2-trichloro-ethyl ester (168 mg, 0.387 mmol), 1-(4-trifluoromethyl-phenyl)-ethanol (88 mg, 0.465 mmol), EDCxHCl (111 mg, 0.581 mmol), DMAP (4.7 mg, 0.039 mmol) and DCM (5 mL). The crude was submitted to flash chromatography using heptane and EtOAc (90/10) as eluent to yield the titled compound (157 mg, 67%) as an oil; 1H NMR (400 MHz, CDCl3): δ 1.52 (d, 3H), 3.59 (dd, 2H), 4.52 (s, 2H), 4.96 (s, 2H), 5.90 (m, 2H), 7.09-7.12 (m, 1H), 7.17-7.23 (m, 4H), 7.30-7.42 (m, 4H), 7.57 (d, 2H), 8.08 (d, 1H); Mass spectrum: M−H+ 604.
