1. Preparation of 1-(2,4-dichlorophenyl)-2-(4-methylimidazol-2-yl)ethan-1-one. A solution of 2,4-dichlorobenzoyl chloride (7.24 M) in dichloromethane (25 ml) was added dropwise over 20 minutes to a stirred solution of 2,4-dimethylimidazole (0.80 M) in dichloromethane (75 ml) and N,N-diisopropylethylamine (Huenig’s base) (34 ml). The reaction mixture was cooled during the addition using a water bath. The reaction mixture was then heated to reflux for 5 hours. The reaction can turn a darker color. The product was stripped of solvent under reduced pressure, and the resulting solid was dried in vacuo for one hour. To the dry solid (described above) was added a solution (2:1 v/v, 120 ml) of gla. acetic acid and aq. con. HCl. The mixture was then stirred at reflux for ca. 90 min. The acetic acid was removed via rotary evaporator. Upon cooling, distilled water (200 ml) and toluene (100 ml) were added to the solid residue, which was vigorously stirred for 30 min. The solids were filtered, rinsed with 50 ml distilled water, and discarded. The filtrate was transferred to a separatory funnel. After the organic layer was discarded, the aqueous layer was washed with toluene (2¡Á100 ml). The aqueous layer was transferred to a large beaker (2 L) and diluted with isopropyl ether (50 ml). The stirred mixture was basified (pH 7-8) by careful addition of sodium bicarbonate which leads to the formation of a sticky white solid. Dichloromethane (200 ml) was added and stirring continued for 10 min. The organic layer was separated and the aqueous layer was again extracted with dichloromethane (100 ml). The organic layers were combined and washed with sat. aq. NaHCO3 (100 ml), distilled water (100 ml), brine (100 ml), dried with Na2SO4, filtered, concentrated, and dried in vacuo giving 1-(2,4-dichlorophenyl)-2-(4-methylimidazol-2-yl)ethan-1-one in 46% yield.
