摘要: Process for preparing 1-alkyl-5-nitroimidazoles of formula: ##STR1## which comprises reacting an alkyl sulphate with an imidazole derivative of general formula: ##STR2## in an organic solvent, and then hydrolyzing or alcoholyzing the product obtained. In the formulae (I) and (II), R denotes hydrogen, unsubstituted or substituted alkyl, aryl or cycloalkyl. In the formula (I), R.sub.1 denotes alkyl. In the formula (II), X denotes a group which can be removed by hydrolysis or alcoholysis.
