Hydrochloric Acid → (5,6-Dichloro-1H-indol-3-yl)acetic acid

Participants

Reaction Steps

A mixture of ethyl 2-(5,6-dichloro-1H-indol-3-yl)acetate (120 mg, 0.44 mmol), LiOH (90 mg, 2.20 mmol) in THF (3 mL) and H2O (1 mL) was stirred at RT for 16 h. The solution was poured into water, adjusted pH to 3-4 with 1N HCl and extracted with ethyl acetate. The organic layer was dried over Na2SO4 and concentrated in vacuo to afford the desired product (90 mg, 84.5% yield) as a yellow solid.
