Reaction Steps

214 mg (0.63 mmol) 6-[4-(2-oxo-2,3-dihydro-imidazo[4,5-b]pyridin-1-yl)-piperidin-1-yl]-pyrimidine-4-carboxylic acid, 100 mg (0.628 mmol) spiro[cyclobutane-1,3′-indoline], 212 mg (0.66 mmol) TBTU and 168 μL (1.20 mmol) triethylamine in 4 mL DMF were stirred overnight at RT. The mixture was separated by preparative HPLC. The product fractions were combined and the acetonitrile was removed using the rotary evaporator. The precipitated substance was suction filtered, washed with 20 mL water and dried in the CAD at 50° C.
