Reaction Steps

103 mg (0.40 mmol) 5-amino-1,3-dihydrospiro[indene-2,3′-pyrrolo[2,3-b]pyridin]-2′(1′H)-one, 113 mg (0.40 mmol) (6-chloro-pyrimidin-4-yl)-(2-ethyl-2,3-dihydro-indol-1-yl)-methanone and 13 μL of a 4 molar aqueous hydrochloric acid solution were added to 2.0 mL of 2-propanol and the mixture was refluxed for 2 h. Then the reaction mixture was evaporated down and purified by preparative HPLC-MS. The product-containing fractions were combined and the organic solvent was evaporated down. The residue was made alkaline with a 1N aqueous sodium hydroxide solution, the precipitate formed was suction filtered, washed with water and dried under HV.
