Reaction Steps
A solution of ethyl 2-(furan-2-yl)-2-hydroxyacetate (11.05 g, 64.5 mmol), trimethylorthoacetate (29.8 mL, 387 mmol) and hexanoic acid (2 mL) in decalin (195 mL) is heated at 180° C. for 12 hours. The reaction is cooled and extracted with methanol to provide a mixture of diester and decalin. This mixture is dissolved in methanol (250 mL), cooled to 0° C., treated with 2 M NaOH (150 mL) and stirred for 12 hours. The methanol is removed and the crude reaction is extracted with ether, and the basic layer is acidified with 6 N HCl and extracted with ethyl acetate. The organic layer is washed with brine, dried and concentrated to give 2,3-di(carboxymethyl)furan.
