Vorschrift

150 mg (0.47 mmol) TBTU were added to 150 mg (0.44 mmol) 6-[4-(2-oxo-2,3-dihydro-imidazo[4,5-b]pyridin-1-yl)-piperidin-1-yl]-pyrimidine-4-carboxylic acid, 75 mg (0.46 mmol) 5-nitro-2,3-dihydro-1H-indole, 100 μL and (0.712 mmol) triethylamine in 1.5 mL DMF and the mixture was stirred overnight at RT. The reaction mixture was poured onto 30 mL water. The precipitated product was suction filtered and dried at 50° C. in the CAD.
