A solution of N-(5-(3-(9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-yl)pyridin-2-ylamino)pyridin-2-yl)acetamide (18.8 mg, 44 μmol) in 5 N aqueous HCl (1 mL) was heated at 95° C. for 1 h, after which time LCMS indicated conversion to desired product. The solution was made slightly alkaline with 5 N aqueous NaOH (about pH 8) and the resulting precipitate was collected by filtration, washing with water, and dried to give N3-(3-(9H-purin-6-yl)pyridin-2-yl)pyridine-3,6-diamine (6.0 mg, 45% yield) as a dark solid. 1H NMR (d6-DMSO, 400 MHz) δ 12.17 (bs, 1H), 9.74 (d, 1H), 8.98 (s, 1H), 8.55 (s, 1H), 8.21 (m, 2H), 7.77 (dd, 1H), 6.89 (dd, 1H), 6.49 (d, 1H), 5.65 (bs, 3H); m/z (API-ES) 305, (M+H)+.
