Procedure

(6-(6-methoxypyridin-3-ylamino)-5-(2-methyl-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-yl)pyridin-3-yl)(4-(methylsulfonyl)phenyl)methanol (the crude material from the previous step) was suspended in MeOH (5.0 mL) and aqueous hydrochloric acid (5 N, 0.50 mL, 2.5 mmol) was added. The reaction was stirred at room temperature for about 2 h, and then was diluted with DCM and MeOH. After 3.5 h, the suspension was filtered. Neither solid nor filtrate was >95% pure by HPLC, so they were combined, concentrated, treated with water, and filtered. The solid was collected, treated with DMSO and TFA, and filtered through a Celite® (diatomaceous earth) pad. The filtrate was purified by prep HPLC (10% to 100% MeCN/water with 0.1% TFA over 28 min with a total flow rate of 100 mL/min.) to give (6-(6-methoxypyridin-3-ylamino)-5-(2-methyl-9H-purin-6-yl)pyridin-3-yl)(4-(methylsulfonyl)phenyl)methanol (122.4 mg, 56% yield over two steps). 1H NMR (d6-DMSO, 400 MHz) includes δ 12.62 (br s, 1H), 9.84 (br s, 1H), 8.62 (s, 1H), 8.52 (d, J=2.54 Hz, 1H), 8.29 (d, J=2.15 Hz, 1H), 8.16 (dd, J=8.71 Hz, 2.64 Hz, 1H), 7.90 (d, J=8.22 Hz, 2H), 7.73 (d, J=8.22 Hz, 2H), 6.84 (d, J=8.80 Hz, 1H), 5.91 (s, 1H), 3.84 (s, 3H), 3.17 (s, 3H), 2.84 (s, 3H). m/z (ESI, pos. ion) 518 (M+H)+.
