Procedure

DOWEX® 50W-X2 (2 g), benzyl formate (10 mL, mol), and adipic acid (2 g, mol) were added to octane (10 mL). The mixture was refluxed for 4 hours at 100° C., and the crude product was purified via silica chromatography to yield a clear, colorless liquid (87% yield). 1H NMR (CDCl3) 1.59-1.78 (m, 4H, CH2CH2), 2.33-2.39 (m, 4H, CH2COOH), 5.09 (s, 2H, PhCH2), 7.25-7.30 (m, 5H, aromatic).
