Reaction Steps

150 mg (0.40 mmol) 2-(2′-oxo-1,1′,2′,3-tetrahydrospiro[indene-2,3′-pyrrolo[2,3-b]pyridin]-5-ylamino)isonicotinic acid, 55 μL (0.42 mmol) 2-methylindoline, 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.
