Reaction Steps

A solution of ethyl 9-bromo-8-fluoro-3,4,5,6-tetrahydro-4,6-methanobenzo[3,4]cyclohepta[1,2-d]imidazole-2-carboxylate (80 mg, 0.22 mmol) in methanolic ammonia (10 mL of a 7M ammonia solution in methanol) was warmed to 40° C. for 3d in a pressure tube. Evaporation of the reaction mixture in vacuo furnished the title compound (77 mg, 0.22 mmol, 100%) as a colorless solid: 1H NMR (500 MHz, d4-methanol) δ 1.62-1.69 (m, 2H), 2.92-3.01 (m, 2H), 3.45-3.50 (m, 1H), 3.65-3.72 (m, 1H), 6.97-7.02 (m, 1H), 8.42-8.50 (m, 1H); M+1=336/338.
