Ethylene Glycol → HCID 11333948, compound

Participants

Reaction Steps

4-(3-cyanophenyl)-3-cyclohexene-1-one (from step 1 of method 2, 1.8 g, 9.0 mmole), ethylene glycol (2.8 g, 45 mmole) and p-toluenesulfonic acid monohydrate (0.1 g, 0.5 mmole) were dissolved in 50 ml toluene. The reaction was refluxed for 2 hours. The organic layer was washed with water (2×50 mL) and dried over sodium sulfate. The residue from the organic layer was purified by column chromatography using ethyl acetate/hexane (15/85) as the eluent to afford 4-(3-cyanophenyl)-3-cyclohexene-1-one ethylene ketal(1.9 g, 87%).
