Reaction Steps
21 g (520 mmol) of 60% sodium hydride are suspended in 700 ml of anhydrous DMF under an inert atmosphere, and the mixture is cooled to 0° C. 40.5 g (260 mmol) of 2,2,2-trifluoro-N-isopropylacetamide are slowly added portionwise. After 15 minutes, 62 ml (520 mmol) of 1,4-dibromobutane are added. The reaction medium is then heated at 60° C. for 3 hours, and then cooled to room temperature, poured into 1 L of water and extracted with ethyl acetate. The organic phase is washed with water and dried, and the residue obtained is purified by distillation. A colorless oil is obtained (m=0.18 g, yield=24%).
