1-(Ethoxycarbonyl)cyclopropanecarboxylic acid was synthesized as follows: A solution of diethyl 1,1-cyclopropanedicarboxylate (20 g) in 1N NaOH (107 mL) and ethanol (220 mL) was hydrolyzed for 16 hours. Ethanol was removed by減壓蒸餾. The remaining starting material was extracted with ethyl acetate. The aqueous layer was acidified with 1N HCl. The reaction mixture was then extracted with ethyl acetate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography to afford 1-(ethoxycarbonyl)cyclopropanecarboxylic acid in 94% yield. 1H NMR (CDCl3) δ 1.06 (t, 3H), 1.53 (m, 2H), 1.62 (m, 2H), 4.21 (q, 2H). ESI-MS: m/z 159 [M+H]+ for C7H10O4.
