Participants

Reaction Steps

A mixture of 73 mg of (1RS,3S)-3-butyl-1-cyanocyclopentane (prepared in Reference Example 13), 0.6 ml of conc. sulphuric acid, 0.6 ml of acetic acid and 0.6 ml of water was stirred for 1 hr. at 110° C. To the reaction solution, 30 ml of ethyl acetate and 20 ml of water were added. The oily layer which separated was washed with water, dried over anhydrous magnesium sulphate, and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel using a mixture of cyclohexane and ethyl acetate (2:1) as eluent to give 30 mg of the title compound having the following physical characteristics, in a 36.5% yield.
