Reaction Steps

To a solution of {[4-(trifluoromethyl)pyridin-2-yl]methoxy}acetic acid (450 mg, 1.9 mmol) and tert-butyl (3S)-pyrrolidin-3-ylcarbamate (360 mg, 1.9 mmol) in DMF (10 mL) was added benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (880 mg, 2.0 mmol) followed by triethylamine (0.80 mL, 5.7 mmol). After being stirred at room temperature overnight, ethyl acetate was added. The solution was washed with 1 N NaOH and water. Purification on silica gel column eluting with EtOAc provided the title compound (300 mg) as a clear oil. MS (M+H) 404.3.
