Reaction Steps
Combine [4-(tert-butoxycarbonylaminomethyl)-phenyl]-acetic acid (400 mg, 1.5 mmol), isopropylamine (0.14 mL, 1.65 mmol), EDC (345 mg, 1.8 mmol), HOBt (243 mg, 1.8 mmol), triethylamine (0.63 mL, 4.5 mmol) and DMAP (18.3 mg, 0.15 mmol) in anhydrous DCM (15 mL). Stir at room temperature for 1 day under nitrogen. Concentrate in vacuo and purify the crude mixture by chromatography on silica gel eluting with hexane/EtOAc (1:1) to obtain the desired intermediate as a white solid (426 mg, 92%). MS (ES+) m/z: 324 (M+NH4+)+.
