実験手順: After a mixture of 5.7 grams (0.034 mole) of 2,6-dimethoxyphenylmethanol in 40 mL of concentrated hydrobromic acid was stirred at ambient temperature for about one hour, the reaction mixture was taken up in diethyl ether. Solid sodium chloride was added to the mixture to obtain a phase separation. The organic layer was separated and concentrated under reduced pressure, yielding about 4.7 grams of 2,6-dimethoxyphenylmethyl bromide. This compound was used immediately in the next reaction. to obtain a phase separation The organic layer was separated concentrated under reduced pressure

実験手順: A solution of 2,6-Dimethoxylbenzyl alcohol (3.33 g, 19.8 mmol) and diisopropyl azodicarboxylate (DIAD, 4.36 g, 21.6 mmol) in THF (30 ml) was added drop wise to a solution of Ethyl 2-(3-hydroxyphenyl)acetate (4 g, 22.2 mmol) and triphenylphosphine (5.66 g, 21.6 mmol) in THF (80 ml). The reaction mixture was stirred at room temperature for 8 hours, diluted with ether and washed with water and brine. The organic layer was dried over Na2SO4, filtered, concentrated, and purified by flash chromatography on a silica gel column (hex:ethyl acetate 4:1) to give the title compound. washed with water and brine The organic layer was dried over Na2SO4 filtered concentrated purified by flash chromatography on a silica gel column (hex:ethyl acetate 4:1)
