Versuchsvorschrift

(4-{[(4-tert-Butyl-phenyl)-carb oxy-methyl]-amino}-benzoic acid tert-butyl ester (760 mg, 2.0 mmol), was taken up in 5 mL of DMF followed by addition of HOBt (765 mg, 5.0 mmol) and EDCT (958 mg, 5.0 mmol). The reaction was stirred at RT for 30 min, 4-iodoaniline (657 mg, 3 mmol) was added followed by Hunig's base (640 mg, 5 mmol) and allowed to stir an additional 16 h at RT. Ethyl acetate (20 mL) and 20 mL water were added and separated. The aqueous layer was then back extracted with another 10 mL of EtOAc, the organic layer were combined and washed with water (3×20 mL). The organic layer was dried over sodium sulfate, filtered and the solvent was removed under reduced pressure to give a brown solid. The solids were triturated with methanol to give a white solid (818 mg, 70%). 1H NMR (CDCl3): δ 1.32 (9H, s), 1.58 (9H, s), 4.89 (2H, d), 5.02 (1H, d), 6.62 (2H, d, J=8.4 Hz), 7.22-7.95 (10H, m), 8.81 (1H, s).
