Procedure

To a solution of (5-methyl-thiophen-2-yl)-phenylamino-acetic acid hydrochloride (I268) (220 mg, 0.77 mmol), (R)-quinuclidin-3-ol (338 mg, 2.66 mmol) and 1H-benzo[d][1,2,3]triazol-1-ol (180 mg, 1.33 mmol) in dry THF (15 mL), is added PS-DCC (1.0 g, 1.330 mmol) and the mixture is shaken at RT for 15 hours. Then (R)-quinuclidin-3-ol (49.3 mg, 0.39 mmol) and PS-DCC (291 mg, 0.39 mmol) are added again and the reaction is shaken at RT for other 3 hours. The resin is filtered off and washed several time with EtOAc. The solvent is concentrated and washed with aq. NaHCO3, water and brine. The organic phase is dried over Na2SO4 and evaporated to obtain the title compound as a brown oil (175 mg, 63% yield).
