Lithium hydroxide, monohydrate → 3-(4-Chloro-2-methylphenoxy)propionic acid

Participants

Reaction Steps

A solution of LiOH.H2O (0.50 g; 12 mmol) in water (10 mL) was added to a solution of ethyl 3-(4-chloro-2-methylphenoxy)propionate (1.98 g; 8.15 mmol; from step (i) above) in THF (20 mL). The reaction mixture was stirred at room temperature overnight, THF was evaporated and the water phase was washed with ether. The resultant solution was acidified with HCl (2M), whereafter a solid material precipitated. The product was filtered and air-dried yielding 0.62 g (35%) of the sub-title compound.
