Reaction Steps

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 5N 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 6N 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)+.
