Reaction Steps
Into a mixture of methanol (10 ml) and tetrahydrofuran (14 ml), methyl 2-[4-(6-chloro-2-quinoxalinyloxy)phenoxy]propionate (0.6 g) was dissolved, and lN sodium hydroxide solution (2.5 ml) was added thereto. The reaction was carried out at room temperature while stirring for 2 hours. After removal of methanol and tetrahydrofuran by distillation, the aqueous layer was washed with dichloromethane (1 ml), made acidic with conc. hydrochloric acid and extracted with ethyl acetate. The extract was concentrated to remove ethyl acetate to give 2-[4-(6-chloro-2-quinoxalinyloxy)phenoxy]propionic acid (0.44 g). Yield, 76%.
