Versuchsvorschrift

A solution of 6-methoxy-N-(3-(9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-yl)pyridin-2-yl)pyridin-3-amine (190 mg, 471 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 and stand overnight. An essentially clean conversion was observed. The solution was neutralized with aqueous ammonia, and the precipitated product was collected by filtration washing with a small volume of water and dried under vacuum. N-(6-methoxypyridin-3-yl)-3-(9H-purin-6-yl)pyridin-2-amine (120.4 mg, 80.1% yield) was obtained as an orange solid. 1H NMR (400 MHz, DMSO-d6) δ 13.80 (br. s., 1H); 12.33 (br. s., 1H); 9.73 (br. s., 1H); 9.10 (s, 1H); 8.70 (s, 1H); 8.50-8.58 (m, 1H); 8.25-8.34 (m, 1H); 8.08-8.20 (m, 1H); 6.95-7.07 (m, 1H); 6.79-6.90 (m, 1H); 3.85 (s, 3H). m/z (ESI, +ve) 320.0 (M+H)+.
