Ethylene carbonate → HCID 13939035, compound

Participants

Reaction Steps

4-(1-Methylpropoxy)phenol (6.92 g, 41.6 mmol), ethylene carbonate (7.34 g, 83.2 mmol) and DMF (456 ml) are mixed under N2. With stirring, the mixture is degassed (3X) by alternate application of vacuum and N2. Potassium carbonate (11.51 g, 83. 2 mmol) is then added, under N2, and the mixture is heated at 90° for 27 hours. The reaction mixture is then poured into ice water and 10 ml of 40% potassium carbonate solution is added to increase the pH to 13. The aqueous phase is extracted with ether (3X) and the organic layers are washed with 40% KOH, the water until neutral and with brine, dried, filtered and the solvent evaporated to give 2-[4-(1-methylpropoxy)phenoxy]ethanol.
