A new synthesis of N-(α-methoxyarylmethyl)-2, 2-dimethylaziridines is presented. Different benzaldehydes were converted into the corresponding imines upon reaction with 2-bromo-2- methylpropylamine. Treatment of the latter imines with sodium methoxide afforded N-(α- methoxyarylmethyl)-2, 2-dimethylaziridines in good yields.
