Versuchsvorschrift
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-morpholinoethyl)pyridin-2-ylamino)pyridin-3-yl)methanesulfonamide (0.165 g, 0.263 mmol) and 5 N hydrochloric acid (0.5 mL, 2.5 mmol) were mixed into THF (3 mL). The solution was stirred at room temperature for 30 min. 10 mL of buffer (pH 5, citric acid/NaOH) was added and the pH was further adjusted to about 5 by adding a few drops of 6 N NaOH. The aqueous phase was extracted with 10% isopropanol in chloroform (3×20 mL). The combined organic phases were dried over sodium sulfate, filtered and concentrated in vacuo. The crude product was purified by preparative HPLC using a Phenomenex, Gemni 5 micron C18 100×30 mm column (1% to 90% CH3CN w/0.1% TFA/H2O w/0.1% TFA in 10 min). The corresponding fractions were collected and concentrated down to dryness. The residue was treated with about 5 mL of pH 5 buffer and pH 7 buffer were added to adjust pH to about 6. The aqueous phase was extracted with 10% isopropanol in chloroform (3×20 mL). The combined organic phases were dried over sodium sulfate, filtered and concentrated in vacuo to afford 0.101 g of yellow solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 13.65 (br. s., 1H) 13.11 (br. s., 1H) 9.82 (br. s., 1H) 9.68 (br. s., 1H) 8.71 (d, J=1.96 Hz, 1H) 8.66 (s, 1H) 8.53 (s, 1H) 8.34 (d, J=1.17 Hz, 1H) 3.50-3.67 (m, 5H) 3.15 (s, 3H) 2.88 (s, 3H) 2.35-2.46 (m, 2H) 1.42 (d, J=6.65 Hz, 3H).
