Reaction Conditions

Reaction Steps

To a solution of tert-butyl 2-chloro-4-isopropylbenzoate (150 mg, 0.59 mmol) in dichloromethane (10 mL) was added 2,2,2-trifluoroacetic acid (2 mL) at room temperature. The resultant reaction mixture was stirred at 30° C. for 30 minutes. Thin layer chromatography showed that starting material was consumed completely. The solution was concentrated under reduced pressure to give 2-chloro-4-isopropylbenzoic acid (100 mg, 85.5%) as a white solid which was used in the next step directly. LRMS (M+H+) m/z: calcd 199.04. found 199.
