3.55 g of this diethyl hydroxyterephthalate was dissolved in 100 mL dimethylformamide and combined with 640 mg of crushed sodium hydroxide. 4.03 g of 4-bromo-1-butene dissolved in 20 mL of dimethylformamide was added dropwise in while cooling on an ice bath. After stirring the reaction for 16 hours, purification by the usual methods gave 1.74 g of diethyl 2-(3-butenyloxy)terephthalate.
