Sodium hydride → 8-(6-Formylnaphthalen-2-yloxy)octanoic acid

Participants

Reaction Steps

The intermediate aldehyde for this compound was prepared by a slightly modified procedure: 6-Hydroxynaphthalene-2-carbaldehyde (1.0 g, 5.8 mmol) was dissolved in DMF (10 mL) and sodium hydride 60% (278 mg) was added and the mixture stirred at RT for 15 min. 8-Bromooctanoic acid (0.37 g, 1.7 mmol) was converted to the sodium salt by addition of sodium hydride 60% and added to an aliquot (2.5 mL) of the above naphtholate solution and the resulting mixture was stirred at RT for 16 hours. Aqueous acetic acid (10%) was added and the mixture was extracted 3 times with diethyl ether. The combined organic phases were dried with MgSO4 and evaporated to dryness affording 300 mg of 8-(6-formylnaphthalen-2-yloxy)octanoic acid.
