Participants

Reaction Steps

3-(4-Carboxymethyl-phenyl)-2-[2-(4-fluoro-phenyl)-ethanesulfonyl]-propionic acid 2,2,2-trichloro-ethyl ester (121 mg, 0.23 mmol) was dissolved in anhydrous DMF (2.0 mL) and TBTU (147 mg, 0.46 mmol), N-methyl morpholine (46.5 mg, 0.46 mmol) and 4-(trifluoromethyl)benzyl alcohol (81.06 mg, 0.46 mmol) were added under nitrogen atmosphere. The reaction was stirred at ambient temperature for 18 h. EtOAc was added and the mixture was extracted with water and brine. After drying the organic layer over Na2SO4 the solvent was evaporated under reduced pressure to afford the crude product as an oil (161 mg, 102.3%). No further purification was done. 1H NMR (400 MHz, CDCl3): δ 7.44-7.62 (m, 6H), 7.12-7.23 (m, 4H), 6.97-7.02 (t, 2H) 5.14 (s, 2H), 4.74 (s, 2H), 4.69 (d, 1H), 3.62 (s, 2H), 3.34-58 (m, 4H), 3.15-3.19 (t, 2H).
