PROCEDURE

实验过程

To a solution of methyl 2-[4-(3-chloro-5-trifluoromethyl-2-pyridyloxy)phenoxy]propionate (1.75 g) in methanol (15 ml) is added potassium hydroxide (1.0 g) in water (10 ml). The resulting mixture is stirred at RT until a clear solution is obtained (about 20 min). Most of the methanol is removed, and the aqueous solution is acidified with dilute HCl and extracted with ether. The combined ether extracts are dried and concentrated to dryness to give 2-[4-(3-chloro-5-trifluoromethyl-2-pyridyloxy)-phenoxy]propionic acid.
