Participants

Reaction Steps

14.7 μl (0.14 mmol) 3-pentanol, 40 mg (0.14 mmol) N-(1-(4-((4-hydroxyphenyl)-ethynyl)phenyl)propan-2-yl)acetamide (I74.1) and 69.8 mg (0.21 mmol) polymer bound triphenylphosphine (˜3 mmol/g) are added to 1 mL THF followed by 31.4 mg (0.14 mmol) DBAD. After stirring the mixture for 2 h at r.t. further 7.5 μl (0.07 mmol) 3-pentanol and 16 mg (0.07 mmol) DBAD are added and stirring is continued for 72 h. The reaction mixture is filtered and the filtrate is purified by HPLC (MeOH/H2O/TFA).
