실험 절차
A mixture of 10 g (80.6 mmol) of 3-(hydroxymethyl)phenol, 78.4 g (241.7 mmol) of Cs2CO3 and 8.4 mL (88.6 mmol) of bromoethyl methyl ether in 150 mL of CH3CN is heated for 12 hours at 110° C. After cooling to room temperature, the medium is filtered, concentrated under reduced pressure, taken up in 500 mL of DCM, washed with brine (2×100 mL) dried over Na2SO4, filtered and then concentrated under reduced pressure. 10.9 g of 3-(2-methoxyethoxy)phenyl]methanol are obtained in the form of a yellow oil.
