Procedure

N-[2-[3-Amino-4-methoxyphenyl]ethyl]-2,2,2-trifluoro acetamide (2.62 g, 0.01 moles) in dry dimethylformamide (50 ml) was added dropwise with stirring to sodium hydride (0.3 g., 80% oil dispersion, 0.01 moles) in dry dimethylformamide (50 ml) under nitrogen. The solution was warmed at 60° for 30 min then cooled and N-(6-bromohexyl)-2,2,2-trifluoro-N-(2-phenylethyl)acetamide (3.80 g., 0.01 mole) was added. The solution was stirred for 4 hours then quenched with water and extracted with ethyl acetate. The extracts were washed with water dried and evaporated to give crude N-[2-(3-amino-4-methoxyphenyl)ethyl]-N'-(2-phenylethyl)-1,6-hexanediylbis (2,2,2-trifluoroacetamide) (3.1 g) as a pale brown oil.
