Reaction Steps

A mixture of 2-(1-((2-(2-aminophenylamino)-9-methyl-6-morpholino-9H-purin-8-yl)methyl)piperidin-4-yl)propan-2-ol (177 mg, 0.368 mmol) in acetic acid (1.5 mL) was stirred at reflux for 5 hours. The reaction mixture was then concentrated and then purified first by flash chromatography (10% MeOH in DCM containing 1% 2 M ammonia in MeOH), followed by RP-HPLC to give 157 (0.0373 g, 21.1%). LCMS: M+H+=505.3. 1H-NMR (400 MHz, DMSO-d6): δ 8.09 (m, 1H), 7.60 (m, 1H), 7.25 (m, 2H), 4.26 (s, br, 4H), 4.02 (s, 1H), 3.83 (s, 3H), 3.78 (m, 4H), 3,73 (s, 2H), 2.90 (m, 2H), 2.84 (s, 3H), 1.99 (m, 2H), 1.66 (m, 2H), 1.21 (m, 3H), 1.02 (s, 6H).
