Procedure

The ethyl 3-(4-nitrophenyl)acrylate (512.8 mg) obtained in the above step (a) was dissolved in dioxane (5.1 ml), and the solution was added with 5 N sodium hydroxide (2.78 ml) and stirred at room temperature for 3.5 hours. Separation and extraction with diethyl ether was made to remove impurities, and then: 5 N hydrochloric acid was added to the aqueous layer to reduce the pH to 2. The precipitated crystals were collected by filtration to obtain 3-(4-nitrophenyl)acrylic acid (270.1 mg, 60.3%).
