Procedure

Dimethyl 1,1-cyclopropanedicarboxylate (5 ml) was mixed with NaOH (1.4 g) in MeOH (40 ml)/water (4 ml). The reaction mixture was stirred at RT overnight and the solvent was evaporated. To the residue was added ether (50 ml), water (50 ml) and extracted once. The aqueous layer was acidified with 6N HCl and extracted three times with ether, the combined organic layer was washed with brine, dried and evaporated to give 1-(methoxycarbonyl)cyclopropanecarboxylic acid (4 g).
