Versuchsvorschrift

[4-(3-Bromo-5-hydroxy-phenylsulfanyl)-2-chloro-phenoxy]-acetic acid ethyl acetate (1.7 g; 4.07 mmol), N-(3-hydroxypropyl)morpholine (0.59 g; 4.07 mmol) and tributylphosphine (1.8 g; 7.33 mmol) were dissolved in THF (100 mL) in a dried reaction flask under an atmosphere of nitrogen. 1,1′-(Azodicarbonyl)dipiperidine (1.85 g; 7.33 mmol) dissolved in THF (50 mL) was added to the reaction mixture, which was stirred at room temperature for 16 h. The reaction mixture was evaporated to dryness and purified by flash chromatography (ethyl acetate: heptane). Yield: 1.1 g. HPLC-MS: m/z: 544.0 (M+); Rt: 1.78 min.
