実験手順
1-[1-(8-Bromo-9-methyl-9H-purin-6-yl)piperidin-4-yl]-1,3-dihydro-2H-benzimidazol-2-one (50 mg, 0.12 mmol) was dissolved in ethanol (1 mL). To this solution was added imidazole (24 mg, 0.35 mmol) and diisopropylethylamine (39 μL, 0.23 mmol). This mixture was irradiated in the microwave at 180° C. for 6 hours. The ethanol was removed in vacuo and replaced by DMA (1 mL). To this solution was added 1 equiv. of sodium hydride. After heating to 100° C. for 1 hour, the mixture was filtered and purified by prep HPLC to obtain 24 mg of the desired product. 1H NMR (400 MHz, DMSO-d6): δ 10.85 (s, 1H), 8.39-8.28 (m, 1H), 8.27-8.16 (m, 1H), 7.78 (m, 1H), 7.18 (m, 1H), 7.14 (m, 1H), 6.99-6.82 (m, 3H), 5.47 (s, 1H), 4.63-4.40 (m, 1H), 3.67 (s, 3H), 3.22 (m, 3H), 2.42-2.20 (m, 2H), 1.80 (m, 2H). EI (MS) for C21H21N9O, found 416 (MH+).
