Cesium carbonate → 1-neopentyl-4-(4-nitrophenyl)-1H-imidazole

Participants

Reaction Steps

To a solution of 4-(4-nitrophenyl)-1H-imidazole (0.500 g, 2.64 mmol) in N,N-dimethylformamide (10 ml) was added cesium carbonate (1.292 g, 3.96 mmol) followed by 1-bromo-2,2-dimethylpropane (0.366 ml, 2.91 mmol). After heating at 85° overnight, the reaction mixture was cooled to room temperature, diluted with ethyl acetate, washed with water and brine, dried over magnesium sulfate, filtered and concentrated. Normal phase chromatography provided the title compound.
