Procedure
To a solution of methyl 2-cyano-4-methoxy-2-(2-methoxyethyl)butanoate (1.13 g) synthesized according to the method described in European Journal of Organic Chemistry, 2005, vol. 20, pp. 4313-4321 in tetrahydrofuran (10 mL), 1.0 mol/L aqueous sodium hydroxide (20 mL) was added at room temperature, and the mixture was stirred at the same temperature for 7 hours. To the reaction mixture, hexane and tert-butyl methyl ether were added. The aqueous layer was separated, and ethyl acetate and 1.0 mol/L aqueous hydrochloric acid were added. The organic layer was separated, and dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure to obtain 2-cyano-4-methoxy-2-(2-methoxyethyl)butyric acid (G19, 957 mg).
