Dimethylformamide → Methyl [4-({{4-[(4-butylphenyl)ethynyl]benzyl}[(4-cyanoanilino)-carbonyl]amino}methyl)phenoxy]acetate

Participants

Reaction Steps

To a solution of methyl {4-[({4-[(4-butylphenyl)ethynyl]benzyl}amino)methyl]-phenoxy}acetate (37 mg, 0.084 mmol) in anhydrous DCM (2 ml) was added 4-cyanophenyl isocyanate (Aldrich, 45 mg, 0.31 mmol) and the reaction mixture was stirred at rt for 18 hrs. Then PS-trisamine resin (75 mg, Novabiochem, 3.5 mmol/g) and DMF (1 mL) were added and the resulting mixture was stirred at rt for 5 additional hrs. Removal of the resin by filtration followed by evaporation of the solvents gave 65 mg (97%) of the title compound as a pale yellow oil. HPLC, Rt: 5.7 min (purity: 74.1%).
