With trimethylsilyl bromide In dichloromethane for 6h; Inert atmosphere; Experimental Procedure 2.2. Synthesis of (2-(9H-carbazol-9-yl)ethyl)phosphonic acid To diethyl(2-(9H-carbazol-9-yl)ethyl)-phosphonate (3.32 g, 10mmol) in dry CH2Cl2 (20mL) trimethylsilylbromide (2.90 mL, 22 mmol) was added under N2. The solutionwas stirred for 6 h before being quenched with MeOH and stirredvigorously. After a further 2 h stirring the solvent was removedunder reduced pressure and water (5 mL) was added. The mixturewas then concentrated under reduced pressure. This step wasrepeated four times to give (2-(9H-carbazol-9-yl)ethyl)phosphonicacid as an off-white solid. The solid was recrystallized with waterto give the white solid (2.91 g, 90.94%). 1H NMR (DMSO, 400 MHz):8.16 (d, 2H, J = 8.0 Hz), 7.56 (d, 2H, J = 12 Hz), 7.48 (t, 2H,J = 8.0 Hz), 7.22 (t, 2H, J = 8.0 Hz), 4.50-4.54 (m, 2H), 2.01-2.09(m, 2H) ppm. 13C NMR: 139.85, 126.32, 122.73, 120.88, 119.42,109.39, 37.83, 28.40 ppm. 31PNMR: 24.05 (s).

With sodium hydroxide In ethanol at 60℃; Experimental Procedure Dissolve 1g of 2-(9H-carbazole-9-ethyl)phosphonic acid diethyl ester in 20 mL of ethanol , add 10 mL NaOH saturated solution, react at 60°C for 24 hours, then add hydrochloric acid dropwise to adjust the pH to acidic, remove the solvent by rotary evaporation after the reaction, then dissolve it in dichloromethane, wash with saturated brine, and then anhydrous The crude product was obtained after drying over magnesium sulfate and concentrating to remove most of the solvent. The crude product was subjected to column purification. The mobile phase was a mixture of ethyl acetate and n-hexane with a volume ratio of 1:4. |
