Procedure

In 20 ml of n-hexane was dissolved 1.40 g (0.011 mol) of 2-ethylhexylamine. With stirring, 1.20 g (0.01 mol) of β-methylcrotonyl chloride was added to the solution. After reaction, the reaction mixture was washed first with diluted hydrochloric acid and then with 10% sodium hydroxide solution and subsequently dried with sodium sulfate. The solvent was distilled off and the residue was further distilled in vacuum. A fraction having a boiling point of 133°-134° C./l mmHg was collected, obtaining 1.76 g of N-(2-ethylhexyl)-β-methylcrotonamide as an oil (yield: 82.3%). Usual analysis was carried out to identify the compound. The results are shown below.
