Participants

Reaction Steps

To a solution of ethyl 2-((4-chloro-2-methoxy-5-(1-methylcyclopropyl)phenyl)amino)acetate (630 mg, 2.12 mmol) in THF (15 mL) and water (5 mL), LiOH.H2O (889 mg, 21.2 mmol) was added and the resulting mixture was stirred at RT for 2 h. The mixture was washed with 20% ethyl acetate/petroleum ether. The aqueous layer was acidified with aqueous HCl (1N) to adjust pH to 3-4 and extracted with ethyl acetate. The organic layer was dried over MgSO4, filtered and concentrated in vacuo to afford the desired product (200 mg, 33% yield).
