Versuchsvorschrift

To a stirred solution of 4-(1-(6-fluoro-5-(2-methyl-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-yl)pyridin-3-yl)ethyl)morpholine (0.157 g, 0.368 mmol) and N-(5-amino-2-chloropyridin-3-yl)methanesulfonamide (Example 330 step 2, 0.103 g, 0.462 mmol) in THF (2 mL) in 20 mL microwave vial, NaHMDS(Aldrich, 1 M in THF, 1.47 mL, 1.47 mmol) was added dropwise at 0° C. The dark red mixture was stirred at 0° C. for 30 min. The mixture was partitioned between a mixture of saturated aqueous sodium chloride (10 mL)/buffer (pH 5.0, citric acid/NaOH) (10 mL) and EtOAc (20 mL). The aqueous phase was extracted with EtOAc (2×20 mL). The combined organic phases were dried over sodium sulfate, filtered and concentrated in vacuo. The crude product was purified by silica gel column chromatography (50 g, eluent: iPrOH in CHCl3 0% to 10%) to afford 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 (0.169 g, 73% yield) as a yellow solid. 1H NMR (400 MHz, CDCl3) δ ppm 13.18 (s, 1H) 9.78 (d, J=1.96 Hz, 1H) 8.83 (d, J=2.54 Hz, 1H) 8.63 (d, J=2.54 Hz, 1H) 8.36 (d, J=2.35 Hz, 1H) 8.31 (s, 1H) 6.76 (br. s., 1H) 5.85-5.90 (m, 1H) 4.17-4.24 (m, 1H) 3.79-3.88 (m, 1H) 3.73 (t, J=4.50 Hz, 4H) 3.51-3.59 (m, 1H) 3.14 (s, 3H) 2.94 (s, 3H) 2.45-2.62 (m, 4H) 2.01-2.22 (m, 3H) 1.66-1.93 (m, 3H) 1.48 (d, J=6.65 Hz, 3H). m/z (ESI, positive ion): 628.0 (M+H)+.
