Procedure
9-Cyclopropyl-6-[4-(2-oxo-2,3-dihydro-1H-benzimidazol-1-yl)piperidin-1-yl]-9H-purine-8-carboxylic acid was prepared in the same manner as 9-methyl-6-[4-(2-oxo-2,3-dihydro-1H-benzimidazol-1-yl)piperidin-1-yl]-9H-purine-8-carboxylic acid. The 8-cyclopropyl-6-methoxy-4-[4-(2-oxo-2,3-dihydro-1H-benzimidazol-1-yl)piperidin-1-yl]pteridin-7(8H)-one (0.836 g, 1.93 mmol) was treated with 2M sodium hydroxide (10 mL, 20 mmol) in methanol at 80° C. for 18 hours gave 0.789 of 9-cyclopropyl-6-[4-(2-oxo-2,3-dihydro-1H-benzimidazol-1-yl)piperidin-1-yl]-9H-purine-8-carboxylic acid as an off-white solid. 1H NMR (400 MHz, DMSO-d6): δ 11.20 (br s, 1H), 8.07 (s, 1H), 6.93 (m, 1H), 6.71 (m, 3H), 5.19 (broad s, 2H), 4.27 (m, 1H), 3.40 (m, 2H), 3.19 (t, 2H), 2.43 (m, 2H), 1.82 (d, 2H), 1.15 (m, 2H), 0.84 (m, 2H). MS (EI) for C21H21N7O4: 420 (MH+).
