Procedure

[4-(3-Hydroxy-5-phenylethynyl-phenylsulfanyl)-2-methyl-phenoxy]-acetic acid ethyl ester (0.25 g; 0.60 mmol), 3-morpholin-4-yl-propan-1-ol (0.12 g; 0.84 mmol) and tributylphosphine (0.27 mL; 1.08 mmol) were dissolved in THF (20 mL) in a dried reaction flask under an atmosphere of nitrogen. 1,1′-(Azodicarbonyl)dipiperidine (0.27 g; 1.08 mmol) dissolved in THF (10 mL) was added to the reaction mixture, which was stirred at room temperature for 16 h. The reaction mixture was evaporated to dryness, acetonitrile added, and the mixture filtered. The solution was purified by prep HPLC (method A). Yield: 150 mg. HPLC-MS: m/z: 546.6 (M+H); Rt: 2.08 min.
