The aroylation of 1-methyl-5-nitroimidazole with aroyl chlorides in the presence of triethylamine leads to 2-aroyl-1-methyl-5-nitroimidazole(I).Beckmann rearrangement of the corresponding oximes (II) yield the anilides (III) as normal Beckmann products.Aroylation of I with p-nitrobenzoyl chloride yields besides the normal derivative (IVa), a minor product (IVB) formed by the attack of a second molecule of the nitroimidazole on the carbonyl carbon.Methyloxalyl chloride similarly yields two products, the major one being the 2-carbomethoxy derivative (VIA).
