Participants

Reaction Conditions

Reaction Steps

To a stirred mixture of 25.00 g (133 mmol) of 6-hydroxy-2-naphthoic acid, 2.21 g (13 mmol) of potassium iodide, 4.28 g (13 mmol) of tetrabutylammonium bromide, and 77 g of ethanol, was added dropwise 18.63 g (332 mmol) of potassium hydroxide dissolved in 38 g of water. The mixture was heated to 60° C., 19.07 g (146 mmol) of 6-chloro-1-hexanol was added dropwise here, and the solution was refluxed for 34 hours. After adding hydrochloric acid dropwise, the reaction mixture was chilled with ice-water, and the precipitate was collected by filtration. Water was added to the precipitate, and the mixture was stirred for 30 minutes and filtered to recover the precipitate, which was dried in an oven at 40° C. overnight. The dried product was recrystallized from THF to yield the desired product, 6-(6-hydroxy-hexa-1-yloxy)-2-naphthoic acid as white solid (21.63 g, Yield: 56.5%).
