Procedure

A solution of 6-methoxy-N-(3-(2-methyl-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-yl)pyridin-2-yl)pyridin-3-amine (95.3 mg, 228 μmol) in 2 N aqueous HCl (2.0 mL, 4 mmol) was heated briefly at 100° C. in an oil bath, and then the heater was turned off and the mixture allowed to slowly cool. The solution was concentrated and purified by SCX ion exchange chromatography washing with MeOH and eluting off with 2 N NH3/MeOH to give N-(6-methoxypyridin-3-yl)-3-(2-methyl-9H-purin-6-yl)pyridin-2-amine (72 mg, 95% yield) as an orange solid. 1H NMR (400 MHz, d6-DMSO) δ 13.60 (br. s., 1H); 12.68 (s, 1H); 9.80 (dd, J=7.82, 1.96 Hz, 1H); 8.60 (s, 1H); 8.54 (d, J=2.69 Hz, 1H); 8.31 (dd, J=4.65, 1.96 Hz, 1H); 8.20 (dd, J=8.92, 2.81 Hz, 1H); 7.00 (dd, J=7.95, 4.77 Hz, 1H); 6.85 (d, J=8.80 Hz, 1H); 3.85 (s, 3H); 2.86 (s, 3H). m/z (ESI, +ve) 334.0 (M+H)+.
