실험 절차

To a solution of 4-cyano-4-[4-(3-pyrrolidin-1-ylpropoxy)-phenyl]-heptanedioic acid dimethyl ester (8.8 g, 21.1 mmol) in 1,2-dimethoxyethane (176 mL) was charged portions of NaH (60% dispersion, 2.55 g, 63.4 mmol). The reaction mixture was heated to reflux. After 4.5 hr, the ¾ of solvent were evaporated and the mixture cooled to 20° C. with an ice bath and quenched with water (100 mL), HCl 1N (100 mL). The aqueous layer was extracted with ether (100 mL). After basification with NaOH the aqueous phases were extracted with dichloromethane. The combined organics were washed with water, dried over Na2SO4, filtered and concentrated to provide 5-cyano-2-oxo-5-[4-(3-pyrrolidin-1-ylpropoxy)-phenyl]-cyclohexane-carboxylic acid methyl ester (6.6 g, 81%) as an oil.
