Reaction Steps
To a solution of 600 mg 4-[2-((S)-2-Cyclobutylcarbamoyl-pyrrolidin-1-yl)-2-oxo-ethoxy]-7-methyl-quinoline-2-carboxylic acid in 60 ml DMF were added 279 μl DIPEA, 294 mg EDC and 234 mg HOBt. After 5 minutes 661 mg 4-[(S)-2-amino-4-(2H-tetrazol-5-yl)-butyryl]-piperazine-1-carboxylic acid butyl ester hydrotrifluoroacetate were added and the mixture stirred for 48 h.
