Procedure

A mixture of 4-[3-(1-quinolin-6-ylcyclopropyl)[1,2,4]triazolo[4,3-b][1,2,4]triazin-6-yl]benzoic acid (40 mg, 0.10 mmol), tert-butyl (2S)-2-amino-3,3-dimethylbutanoate hydrochloride (26 mg, 0.12 mmol), benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (45.5 mg, 0.103 mmol), and N,N-diisopropylethylamine (60 μL, 0.34 mmol) in methylene chloride (1.5 mL) was stirred at RT overnight. The mixture was diluted with DCM, and washed with saturated NaHCO3 solution, water and brine, dried over Na2SO4, filtered, and concentrated to yield desired product which was directly used in the next step without further purification.
