Reaction Steps

2,2,2-Trifluoro-N-(2-phenylethyl)acetamide (21.7 g., 0.1 mole) in dry dimethyformamide (100 ml) was added dropwise with stirring and under nitrogen to sodium hydride (2.4 g ., 0.1 mole, ether washed) in dry dimethylformamide (150 ml). Stirring was continued until a clear solution was obtained and 1,6-dibromohexane (73.2 g., 0.3 moles) was added. The solution was heated at 60°. for 3 hr then poured into water and extracted with ether. The extracts were washed well with water dried and evaporated. Excess dibromohexane was recovered by distillation (b.p. 60°-70°/0.1 mmHg) and the residue was separated on a silica gel column using ether-light petroleum (1:2) as eluant. The major fraction was evaporated to give the title compound as a pale yellow oil (24 g). A sample was distilled to give a colourless viscous liquid, b.p. 146°-152°/0.05 mmHg, (with slight decomposition)
