Methanol → 2-Chloro-3-(1-cyano-1-methylethyl)benzoic acid

Participants

Reaction Steps

To a solution of methyl 2-chloro-3-(1-cyano-1-methylethyl)benzoate (1.67 g, 7.02 mmol) in tetrahydrofuran (24 mL)/methanol (8 mL)/water (8 mL) was added lithium hydroxide•monohydrate (501 mg, 11.9 mmol), and the mixture was stirred at room temperature for 2 hr. The reaction mixture was concentrated under reduced pressure, and 6N hydrochloric acid (2.8 mL) was added dropwise to the residue. The precipitate was collected by filtration, and washed with water to give the title compound (1.43 g, 91%) as a white powder.
