Participants

Reaction Steps

A mixture of trans-4-{6-[(2′-cyanobiphenyl-4-yl)methyl]-5-oxo-7-propyl[1,2,4]triazolo[1,5-a]pyrimidin-4(5H)-yl}cyclohexanecarboxylic acid (0.5 g), 1-hydroxybenzotriazole ammonium salt (0.21 g), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.23 g) and N,N-dimethylformamide (10 mL) was stirred at room temperature for 16 hr. The reaction mixture was diluted with ethyl acetate, washed with water and then with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure and the residue was purified by silica gel column chromatography to give the title compound as a colorless solid (0.36 g, 67%).
