Participants

Reaction Steps

To a solution of 100 mg of 4-[(S)-4-Carboxy-2-({4-[2-((S)-2-cyclobutylcarbamoyl-pyrrolidin-1-yl)-2-oxo-ethoxy]-7-methyl-quinoline-2-carbonyl}-amino)-butyryl]-piperazine-1-carboxylic acid ethyl ester, 48 mg of TOTU and 67 mg of NEM in 2 ml of DCM, 10 mg of hydrazine hydrate was added and the reaction mixture was stirred for 16 h at RT. Then, the reaction mixture was diluted with water and extracted with DCM. The combined organic phases were dried over MgSO4 and the solvents were removed under reduced pressure. The crude product was used for the next reaction step. Yield: 101 mg.
