A mixture of 2-(1-((2-(2-aminophenylamino)-9-methyl-6-morpholino-9H-purin-8-yl)methyl)piperidin-4-yl)propan-2-ol (40 mg, 0.083 mmol) and N,N-carbonyldiimidazole (17 mg, 0.108 mmol) in acetonitrile (2 mL) was stirred at reflux for 15 hours. The reaction mixture was then filtered through paper and purified by RP-HPLC to give 156 (6.7 mg, 16%). LCMS: M+H+=507.2. 1H-NMR (400 MHz, DMSO-d6): δ 11.0 (s, 1H), 7.55 (d, 1H), 7.04 (m, 3H), 4.21 (s, br, 4H), 4.02 (s, 1H), 3.78 (s, 3H), 3.74 (m, 6H), 2.88 (m, 2H), 2.00 (m, 2H), 1.66 (m, 2H), 1.20 (m, 3H), 1.02 (s, 6H)
