Reaction Steps

A mixture of N2-(1-acetyl-3,3-dimethyl-2,3-dihydro-1H-indol-6-yl)-N4-(6-quinolinyl)-2,4-pyrimidinediamine (Example 111, 150 mg, 0.353 mmol) was dissolved in EtOH (6 mL) and 10 drops conc. HCl were added. The mixture was heated to reflux in a sealed tube for 72 h. The crude mixture was poured into EtOAc (125 mL) and sat NaHCO3 (20 mL). The organics were dried over anhydrous MgSO4 and concentrated under reduced pressure. The crude product was purified via medium pressure liquid chromatography using linear gradient starting from 0:100 MeOH/CH2Cl2 ending with 10:90 MeOH/CH2Cl2 as the solvent system to yield the desired product as a light yellow solid. M+H—383; Calc'd for C23H22N6—382.
