Reaction Steps

Phenol (10 g, 106 mmol) was dissolved in 3,4-dihydro-2H-pyran (29 mL, 318 mmol) and one drop concentrated HCl was added at RT. The reaction was stirred at RT overnight. Ethyl ether (500 mL) was added to dilute the reaction. The organic layer was washed with water (2×100 mL), saturated sodium bicarbonate (2×100 mL), brine (2×100 mL) and dried over MgSO4. Evaporation gave title compound (17 g, 100%) as a colorless oil.
