75.25% | Take one 100mL eggplant-shaped bottle, add 0.54g (4.00mmol) 4-hydroxy indoline, 1.36g (4.16mmol) Cs2CO3 and 30mL absolute ethanol, stir at room temperature for 1h, and 0.79g (4.00mmol) 3a- 1 or 3a-2 and 0.10g (0.60mmol) KI were put into the reaction solution, and the reaction was refluxed at 80C for more than 4h. The progress of the reaction was monitored by thin layer chromatography until the <strong>[85926-99-4]4-hydroxyindoline</strong> point completely disappeared, and vacuum distillation The solvent was removed, and the residue was a brown solid. The residue was dissolved with 30 mL each of water and ethyl acetate. The liquid was separated, and the aqueous phase was extracted twice with ethyl acetate, 15 mL each time. The organic phases were combined, washed with water, and washed with saturated brine. Sodium sulfate was dried over water, the sodium sulfate was filtered off, and the filtrate was distilled off under reduced pressure to remove the solvent. The residue was mixed with 100-200 mesh silica gel and separated by column chromatography (PE:EA=10:1 elution) to give a light yellow oil 4 -((Indoline-4-)oxymethyl)benzaldehyde (4d-1, 0.61g, yield 60.40%) or 3-((Indoline-4-)oxymethyl)benzaldehyde ( 4d-2, 0.76g, yield 75.25%). |
