To a 20 mL scintillation vial, N′-(2-chloro-5-((3-(2-methyl-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-yl)-5-(1-(4-morpholinyl)ethyl)-2-pyridinyl)amino)-3-pyridinyl)-N,N-dimethylsulfamide (0.047 g, 0.072 mmol) and 5 N hydrochloric acid (0.5 mL, 2.5 mmol) were mixed into THF (2 mL). The solution was stirred at room temperature for 30 min. Buffer (pH 5, citric acid/NaOH) (10 mL) was added and the pH was further adjusted to about 5 using a few drops of 6 N NaOH. The aqueous phase was extracted with 10% isopropanol in chloroform (2×20 mL). The combined organic phases were dried over sodium sulfate, filtered and concentrated in vacuo to afford N′-(2-chloro-5-((3-(2-methyl-9H-purin-6-yl)-5-(1-(4-morpholinyl)ethyl)-2-pyridinyl)amino)-3-pyridinyl)-N,N-dimethylsulfamide (0.0237 g, 58% yield) as a yellow powder. 1H NMR (400 MHz, chloroFORM-d) δ ppm 13.10 (s, 1H) 11.17 (br. s., 1H) 9.81 (br. s., 1H) 8.86 (d, J=2.15 Hz, 1H) 8.51 (d, J=2.35 Hz, 1H) 8.34 (d, J=1.37 Hz, 1H) 8.22 (s, 1H) 6.81 (br. s., 1H) 3.74 (br. s., 4H) 3.56 (d, J=6.65 Hz, 1H) 2.96 (s, 9H) 2.44-2.66 (m, 4H) 1.50 (d, J=6.65 Hz, 3H). m/z (ESI, positive ion): 573.0 (M+H)+.
