After the addition was completed, the resulting solution was stirred for 20 min and then cooled to –78 °C. At this temperature, ethanol (60 mL) was added slowly and the reaction mixture was allowed to warm to room temperature overnight. The precipitate was filtered off and washed subsequently with saturated aqueous sodium hydrogensulfite solution (50 mL) and water (50 mL). The obtained white solid was suspended in methanol (50 mL) and stirred for 1 h at 40 °C. The precipitate was filtered off and recrystallized from chloroform to obtain an off-white powder (6.19 g, 8.23 mmol, 60%).Analysis of the target compound: 1H NMR (400 MHz, CDCl3) δ: 7.47 (d, J = 8.7 Hz, 8H, ArmH), 7.32 (d, J = 8.7 Hz, 8H, AroH), 2.08 (s, 12H, Ad-CH2); 13C NMR (100 MHz, CDCl3) δ: 147.7, 131.5, 126.8, 120.2, 46.8, 39.0.
