A solution of methyl {4-[({4-[(4-butylphenyl)ethynyl]benzyl}amino)methyl]phenoxy}acetate (45 mg, 0.10 mmol) and 4-tert-butylphenylisocyanate (Aldrich, 27 mg, 0.15 mmol) in DCM (2 mL) was stirred at rt overnight in presence of a morpholine resin (1.5 eq., Novabiochem HL, 3.8 mmol/g). Trisamine resin (1.2 eq, Novabiochem, 3.5 mmol/g) was then added and the mixture was stirred at rt for an additional 2 hrs. The reaction mixture was then filtrated and the solvent was removed under reduced pressure to give quantitatively the title compound. HPLC, Rt: 5.97 min purity: 96.3%). M+(ESI): 619.6, M−(ESI): 616.9.
