実験手順
A suspension of N-(4-n-butyl-2-nitrophenyl)-2-bromoacetamide (41 g) in ethanol (200 ml) was treated with a solution of dimethylamine in ethanol (90 ml of 20% w/w). The mixture was refluxed for one hour and the ethanol was evaporated off. Water (100 ml) was added and the mixture extracted with diethyl ether (3 × 200 ml). The extract was dried over magnesium sulphate, filtered and evaporated to give N-(4-n-butyl-2-nitrophenyl)-2-dimethylaminoacetamide as a yellow oil which was used without further purification in the next stage.
