Diisopropylethylamine → 5-(6-(2,3-dihydro-1H-pyrrolo[3,2-c]pyridin-1-carbonyl)pyrimidin-4-ylamino)-1,3-dihydro-spiro[indene-2,3'-pyrrolo[2,3-b]pyridin]-2'(1'H)-one

Reaction Steps

0.15 g (0.37 mmol) 6-(2′-oxo-1,1′,2′,3-tetrahydrospiro[indene-2,3′-pyrrolo[2,3-b]pyridin]-5-ylamino)pyrimidine-4-carboxylic acid hydrochloride, 45 mg (0.38 mmol) 2,3-dihydro-1H-pyrrolo[3,2-c]pyridine, 0.15 mL (0.87 mmol) DIPEA and 0.13 g (0.41 mmol) TBTU in 1.8 mL DMF were stirred overnight at RT. Then the reaction mixture was mixed with water, the precipitate formed was suction filtered and dissolved in DMF/NMP. The purification was carried out by preparative HPLC-MS. The product-containing fractions were combined and lyophilised. A second purification was carried out by preparative HPLC-MS.
