Imidazole → HCID 70606657, compound

Participants

Reaction Steps

of N-2-chlorophenyl-N-propylcarbamoyl chloride, 14g. off imidazole and 30 ml. triethylamine were refluxed in 200 ml. of dry tetrahydrofuran for 5 hours. The reaction mixture was poured into 2 liters of water and the slurry chilled causing some separation from the aqueous phase. A slightly sticky crystalline solid was collected, washed with water and dried in vacuo. It was recrystallised from a mixture of toluene and light petroleum (62°-68° C. fraction) with charcoaling. On cooling, an oil separated which soon solidified to give the product, 1-(N-2-chlorophenyl-N-propylcarbamoyl)imidazole m.p. 75.5°-76.5° C.
