Procedure

A solution of 9.6 g (0.10 M) of 2,4-dimethylimidazole in 50 ml of chloroform and 50 ml of toluene was stirred at room temperature and 3.6 ml (0.05 M) of acetyl chloride was added via syringe over 1 minute. The mixture was stirred at room temperature for 2 hours, then the mixture was filtered to remove insoluble solids, and the filtrate concentrated leaving 6.9 g (100%) of 1-acetyl-2,4-dimethylimidazole as a white crystalline solid: nmr (CDCl3) (δ): 7.00 (s, 1H); 2.68 (s, 3H); 2.57 (s, 3H); 2.21 (s, 3H).
