Reaktionsschritte
To a solution of ethyl 2-(7-bromo-1-(4-chlorophenyl)-3-methylnaphthalen-2-yl)-2-hydroxyacetate (˜2.78 mmol) in t-BuOAc (14 mL) was added 70% perchloric acid (HClO4) (334 μL, 5.56 mmol). After 3 h, water was added. The layers were separated, and the organic layer was dried, filtered, and concentrated in vacuo. The crude material was purified by column chromatography (EtOAc/hexanes) to give the titled compound. 1H-NMR: 400 MHz, (CDCl3) δ: 7.62 (m, 2H), 7.51 (m, 4H), 7.27 (m, 2H), 5.09 (s, 1H), 4.15 (m, 2H), 2.59 (s, 3H), 1.19 (t, J=7 Hz, 3H), 1.00 (s, 9H).
