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 5N 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 5N 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)+.
