Reaction Steps

With stirring and external cooling, 4.80 g of 2-imidazolecarboxaldehyde is added and the cooling bath removed. Slight external heating results in a yellow solution. The reaction mixture is chilled in ice and 10.8 g of 2-nitrobenzyl bromide is added. The reaction mixture is stirred at 0° C. for 18 hours. The volatiles are removed in vacuo to a residue which is stirred with ice water, filtered and the cake washed well with water and suction dried to give 10.9 g of the desired product as a solid, m.p. 141-144° C. MH+ 232.
