Reaction Steps

To a solution of 7-ethoxy-7-oxoheptanoic acid (7.23 g, 385 mmol) in DMF (150 mL) was added tert-Butyl(2-aminophenyl)carbamate (8 g, 385 mmol), HBTU (14.6 g, 385 mmol), DIEA (20 mL, 1155 mmol). The mixture was stirred at room temperature for 12 hours. The resulting mixture was poured into water and extracted by EtOAc (200 mL×3). The organic layers were combined and washed with saturated aqueous solution of Na2CO3, dried over Na2SO4 and then concentrated to give the desired compound (14 g, yield 96.3%).
