Procedure

1.9 g of 1-(4-aminophenyl)-2-ethylimidazole was added to a solution of 2.6 g of p-chlorobenzoyl chloride in 50 ml of toluene, and the mixture was refluxed with stirring for 7 hours. The reaction mixture was naturally cooled and diethyl ether was then added thereto. The precipitated crystal was recovered by filtration, washed sufficiently with ethyl ether and recrystallized from ethanol and then from water to obtain 2.5 g of the intended compound in the form of a hydrochloride. The melting point was 265° to 267° C.
