Procedure
To a solution of tert-butyl 4-isopropyl-3-phenoxybenzoate (150 mg, 0.48 mmol) in dichloromethane (10 mL) was added 2,2,2-trifluoroacetic acid (2 mL). The resultant mixture was stirred at room temperature for 30 minutes. Thin layer chromatography showed that starting material was consumed completely. The solution was concentrated to give 4-isopropyl-3-phenoxybenzoic acid (100 mg, 81.3%) as a white solid which was used in the next step directly. LRMS (M+H+) m/z: calcd 257.11. found 257. 1H NMR (300 MHz, DMSO) δ 12.94 (s, 1H), 7.71 (m, 1H), 7.68 (m, 1H), 7.40 (m, 2H), 7.38 (s, 1H), 7.36 (m, 1H), 7.11 (m, 2H), 1.22 (s, 6H).
