실험 절차

100 mg (0.26 mmol) TBTU were added to 80 mg (0.24 mmol) 6-[4-(2-oxo-2,3-dihydroimidazo[4,5-b]pyridin-1-yl)-piperidin-1-yl]-pyrimidine-4-carboxylic acid, 70.0 mg (0.31 mmol) 7,7-dimethyl-4,5,6,7-tetrahydro-1H-pyrazolo[4,3-c]pyridine dihydrochloride, 120.0 μL (0.86 mmol) triethylamine in 1.0 mL DMF and the mixture was stirred overnight at RT. The reaction mixture was purified by preparative HPLC, the product fractions were combined and then lyophilised.
