Versuchsvorschrift
6 g (39.17 mmol) 2-(2-hydroxyethoxy)aniline A3, 5 ml (5.85 g, 47 mmol) 2-(2-chloroethoxy)ethanol and 8.19 ml (5.95 g, 58.75 mmol) triethylamine were dissolved in 20 ml dimethylformamide and stirred for 4 days at 90° C. After cooling, the solution was filtered, the precipitate washed with dichioromethane and the filtrate concentrated in vacuo. The residue was taken up in chloroform and washed twice with a small quantity of water. The chloroform solution was then dried over sodium sulfate and concentrated. The viscous crude product was purified by column chromatography on silica gel 60 with toluene/acetone 1:2 as the mobile phase. 5 g of brown, viscous oil were obtained; yield 53%.
