Reaction Steps

To 0.015 g (0.15 mmol) furan-2-ylmethanol in 0.75 mL THF are added 0.03 g (0.10 mmol) N-Ethyl-2-[4-(4-hydroxy-phenylethynyl)-phenyl]-propionamide (XVIII.2) and 40 mg polymer-bound triphenylphosphine (3 mmol/g resin). The mixture is cooled to 0° C. and 0.03 g (0.15 mmol) di-tert-butyl azodicarboxylate dissolved in 0.5 mL THF are added. The mixture is stirred over night at rt. After that time additional 0.03 g (0.15 mmol) di-tert-butyl azodicarboxylate dissolved in 0.5 mL THF are added and stirring is continued over night. Subsequently the mixture is filtered (Alox), washed (DMF/MeOH 9:1) and concentrated. The residue is dissolved in DMF and the desired product was purified using RP-HPLC (narrow gradient, water/MeOH+0.1% TFA).
