Procedure

In 2 mL of ethanol, were dissolved 115 mg (0.35 mmol) of ethyl 3,3'-(1,4-naphthalenediyl)diacrylate and 196 mg (3.49 mmol) of potassium hydroxide. The solution was refluxed for 2 hours. Thereto, 1N hydrochloric acid was added to bring the solution to pH=1. The deposited crystal was washed successively with water, and ethanol, and dried to obtain 90.2 mg (95%) of 3,3'-(1,4-naphthalenediyl)-diacrylic acid in a yellow crystal state.
