Reaction Steps
4-Formylphenoxyacetic acid (0.306 g, 1.70 mmol) was dissolved in DCM (5 mL). DIEA (0.524 g, 4 mmol) and TBTU (0.550 g, 1.70 mmol) were added followed by tert-butyl N-(2-aminoethyl)carbamate (0.250 g, 1.56 mmol). The mixture was stirred 2 h at room temperature, dissolved in EtOAc and washed sequentially with 5% aqueous K2CO3, KHSO4, water and brine. The extract was dried (MgSO4) and concentrated under reduced pressure to give a yellow solid (0.350 9).
