Imidazole → 1-(4-Nitrophenyl)-1H-imidazole

Participants

Reaction Steps

9.5 g of imidazole were dissolved in 100 ml of DMF, and the resultant solution was further added with 6.1 g of 60% NaH while cooling it with ice. The solution was then stirred for 30 min. and further for 1 hour at room temperature. Then, the solution was added with 20.0 g of 4-chloronitrobenzene and then stirred for 2 hours at a temperature of from 80 to 85° C. The solution reacted was poured into ice water, and the crystals precipitated was filtered and then dried to obtain 22.5 g of 4-(imidazole-1-yl)nitrobenzene.
