N-(2-ethylhexyl)-3-hydroxybutanamide

Conditions: temp:170.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: In a flask, 10 g of N-(2-ethylhexyl)-β-hydroxybutyramide semisuccinate was admitted and heated at 170° C. for 4 hours. The reaction mixture was dissolved in n-hexane and the insolubles were removed by filtration. The filtrate was washed first with diluted hydrochloric acid and then with 10% sodium hydroxide solution, and subsequently dried with sodium sulfate. The residue was recrystallized from n-hexane, obtaining 5.01 g of N-(2-ethylhexyl)-crotonamide (yield: 80.1%). This compound showed substantially the same results as those in Example 1. the insolubles were removed by filtration The filtrate was washed first with diluted hydrochloric acid with 10% sodium hydroxide solution, and subsequently dried with sodium sulfate The residue was recrystallized from n-hexane
