Procedure
To a solution of 6-Benzyloxy-4-hydroxy-4′-trifluoromethyl-biphenyl-3-carboxylic acid (52 mg, 0.13 mmol) in THF:DCE (1:1, 2 mL) was added PS-Carbodiimide resin (0.14 g, 1.3 mmol/g) and 2-(3′-Chloro-4′-fluoro-biphenyl-4-yl)-1-(R)-(3-methyl-[1,2,4]oxadiazol-5-yl)-ethylamine (0.03 g, 0.09 mmol) and stirred for 12 h, resin was filtered and washed with EtOAc (5 mL), filtrate was concentrated and silicagel chromatography of the residue gave pure 6-Benzyloxy-4-hydroxy-4′-trifluoromethyl-biphenyl-3-carboxylic acid [2-(3′-chloro-4′-fluoro-biphenyl-4-yl)-1-(R)-(3-methyl-[1,2,4]oxadiazol-5-yl)-ethyl]-amide (0.013 g).
