Procedure

(4-Trifluoromethyl-phenyl)-methanol (58 mg, 0.332 mmol) was added to a stirred mixture of 2-(3-carboxymethyl-phenylsulfanylmethyl)-benzoic acid 2,2,2-trichloro-ethyl ester (120 mg, 0.277 mmol), EDC×HCl (80 mg, 0.415 mmol), DMAP (3.4 mg, 0.028 mmol) and DCM (4 mL). The reaction mixture was stirred at rt overnight. More DCM was added and the mixture was washed with 0.25M HCl, the organic phase was dried through a phase separator and concentrated. The crude was submitted to flash chromatography using heptane and EtOAc (90/10) as the eluent to yield the titled compound (105 mg, 64%) as a colourless oil; 1H NMR (400 MHz, CDCl3): δ 3.62 (s, 2H), 4.54 (s, 2H), 4.96 (s, 2H), 5.18 (s, 2H), 7.09-7.15 (m, 1H), 7.18-7.24 (m, 4H), 7.30-7.43 (m, 4H), 7.60 (d, 2H), 8.08 (d, 1H); Mass spectrum: M−H+ 590.
