Procedure

To a solution of trans-(4-{(R)-1-[3-({N-[3,5-bis(trifluoromethyl)benzyl]-N-(2-methyl-2H-tetrazol-5-yl)amino}methyl)-6,7-difluoroquinolin-2-yl]pyrrolidin-2-yl}cyclohexyl)acetic acid (85 mg, 0.12 mmol) in DMF (3 mL) is added NH4Cl (10 mg, 0.18 mmol), N-ethyl-N′-(3-dimethylaminopropyl)carbodiimide hydrochloride (EDC.HCl 41 mg, 0.18 mmol), 1-hydroxy-7-azabenzotriazole (HOAt, 24 mg, 0.18 mmol), and small amount of triethylamine. After stirring for 2 hours at room temperature, the reaction mixture is diluted with EtOAc, washed successively with water and brine, and dried over magnesium sulfate. Evaporation of the solvent and purification by silica gel column using ethyl acetate-hexane affords trans-(4-{(R)-1-[3-({N-[3,5-bis(trifluoromethyl)benzyl]-N-(2-methyl-2H-tetrazol-5-yl)amino}methyl)-6,7-difluoroquinolin-2-yl]pyrrolidin-2-yl}cyclohexyl)acetic acid amide.
