Procedure

A mixture of 2-(1-((2-(2-aminophenylamino)-9-methyl-6-morpholino-9H-purin-8-yl)methyl)piperidin-4-yl)propan-2-ol (220 mg, 0.46 mmol) and cyanogen bromide (150 mg, 1.4 mmol) in ethanol (2 mL) was stirred at 95° C. for 15 minutes. The reaction mixture was then loaded onto a Biotage Isolute SPE SCX-2 column. The column was washed with MeOH and the desired product was then eluted with 2 M NH3 in MeOH and further purified by RP-HPLC to give 167 (18.1 mg, 7.8%). LCMS: M+H+=506.3. 1H-NMR (400 MHz, DMSO-d6): δ 8.17 (d, 1H), 7.70 (s, br, 2H), 7.24 (d, 1H), 7.12 (t, 1H), 7.03 (t, 1H), 4.26 (s, br, 4H), 4.10 (s, 1H), 3.84 (s, 3H), 3.80 (m, 4H), 1.73 (m, 2H), 1.27 (m, 3H), 1.03 (s, 6H)
