반응 단계

Diethylamine (1.04 ml, 6.0 mmol) and N,N′-dicyclohexylcarbodiimide (0.64 g, 3.13 mmol) were added to the stirred suspension of 5-[4-(4-(2-amino-2-methoxycarbonylethyl)phenoxy)benzylidene]thiazolidin-2,4-dione hydrochloride (1.3 g, 3.0 mmol), 2-N-t-butoxycarbonylamino-4-imidazole propionic acid (0.8 g, 3.13 mmol) and hydroxylbenzotriazole (0.42 g, 3.13 mmol) in N,N-dimethyl formamide (15 ml). The stirring was continued for 24 h and the reaction mixture was concentrated in vacuum. The obtained residue was washed with 10% sodium bicarbonate, brine and purified with preparative HPLC to yield the title compound (1.5 g, yield 79%).
