Reaction Steps

A solution of trans-methyl 4-(2-(6-fluoro-1H-benzo[d]imidazol-1-yl)-8-oxo-7,8-dihydropurin-9-yl)cyclohexanecarboxylate (5 mg) in THF was treated with an aqueous solution of KOH (35 mg) in 2 mL of water. The mixture was heated at 50° C. for 12 hours. The mixture was acidified with TFA and concentrated. Silica gel chromatography (60:30:10 DCM:EtOAc:MeOH) provided 4.3 mg of the title compound. 1H-NMR (300 MHz, CDCl3) δ 9.0 (s, 1H), 8.3 (dd, 1H), 8.1 (s, 1H), 7.7 (dd, 1H), 7.1 (td, 1H), 4.3 (m, 1H), 2.4 (m, 3H), 2.2 (m, 2H), 1.9 (m, 2H), 1.6 (m, 2H).
