Participants

Reaction Steps

In 270 g of 1,2-dichloroethane were added 108.11 g (1.5 mmol) of acrylic acid, 21.63 g (75 mmol) of 6-(6-hydroxy-hexa-1-yloxy)-2-naphthoic acid obtained in Step 1, 4.28 g (23 mol) of p-toluenesulfonic acid monohydrate, and 0.83 g (7.5 mmol) of hydroquinone, and the solution was refluxed for 4 hours. After evaporation of the solvent, 270 g of water was added to the residue, and the precipitate was collected by filtration and dried in an oven at 40° C. overnight. The dried product was recrystallized from acetone to yield the desired product, 6-(6-acryloyloxy-hexa-1-yloxy)-2-naphthoic acid, as light-yellow powder (16.97 g, Yield: 65%).
