Reaction Steps

N,N-Di-iso-propylethylamine (0.054 g) and 2-(3H-[1,2,3]triazolo[4,5-b]pyridin-3-yl)-1,1,3,3-tetramethylisouronium hexafluorophosphate(V) (0.079 g) were added into a solution of 4-((4-((1-(4-chlorophenyl)cyclopropyl)amino)-6-(2,2,2-trifluoroethoxy)-1,3,5-triazin-2-yl)amino)benzoic acid (0.1 g) and (R)-4-amino-2-((tert-butoxycarbonyl)amino)butanoic acid (0.045 g) in DMF (1 mL). The reaction was stirred at room temperature for 16 hours and (R)-2-((tert-butoxycarbonyl)amino)-4-(4-((4-((1-(4-chlorophenyl)cyclopropyl)amino)-6-(2,2,2-trifluoroethoxy)-1,3,5-triazin-2-yl)amino)benzamido)butanoic acid was isolated by using preparative HPLC system.
