Reaction Steps

150 mg (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, 50 mg (0.42 mmol) 2,3-dihydro-1H-pyrrolo[2,3-b]pyridine, 0.15 mL (0.87 mmol) DIPEA and 130 mg (0.41 mmol) TBTU in 1.8 mL DMF were stirred overnight at RT. The purification was carried out by preparative HPLC-MS. The product-containing fractions were combined and lyophilised. Then the substance was dissolved in DMF and purified again by preparative HPLC-MS. The product-containing fractions were combined and lyophilised.
