Participants

Reaction Steps

Benzyl bromide (1.9 ml) was added to a solution of 1-isopropyl-2-methyl-4,9-dihydro-4,9-dioxo-1H-naphtho[2,3-d]imidazole (0.8 g) in acetonitrile (20 ml) and the mixture was stirred under reflux for 6 hours. After cooling, the resulting precipitate was collected by filtration and washed with ethyl acetate. The obtained solid was recrystallized from methanol to give 1-benzyl-3-isopropyl-2-methyl-4,9-dihydro-4,9-dioxo-1H-naphtho[2,3-d]imidazol-3-ium bromide (0.47 g) as a yellow powder.
