1,5-Dihydroxynaphthalene → 1,5-Bis-(2-ethylhexyloxy)naphthalene

Participants

Reaction Steps

5.0 g of 1,5-dihydroxynaphthalene (31.2 mmol) and 43.1 g of potassium carbonate (311 mmol) were dissolved in 50 mL of dimethylformamide (DMF). 18.0 g of 2-ethylhexyl bromide (93.2 mmol) was added thereto and stirred at 1000 for 24 hours. After the mixture was quenched with water, extracted with ethylacetate, and sequentially washed with water and salt water, excess water was removed using magnesium sulfate, followed by column chromatography, thereby obtaining 8.0 g of the title compound (66.6%).
