Lithium Hydroxide → 1-[(4-Ethoxybenzoyl)amino]cyclopropanecarboxylic acid

Participants

Reaction Steps

Dissolve ethyl 1-[(4-ethoxybenzoyl)amino]cyclopropanecarboxylate (4.25 g, 15.33 mmol) in 1,4-dioxane (60 mL) and add lithium hydroxide (LiOH) (3.22 g, 76.63 mmol) dissolved in water (30 mL). Stir the reaction for approximately 16 hours at ambient temperature. Concentrate the mixture under reduced pressure, add water, acidify with 5N HCl, and collect the precipitate by filtration to give the title compound (2.8 g, 73%) as a white solid: MS (m/z): 248 (M+1).
