実験手順

This compound is prepared essentially by the same method as described in Example 1, Step A-2, except that the 3-hydroxycaprylonitrile is replaced by 1-amino-3(S)-octanol and slightly more than one equivalent of p-toluenesulfonic acid. hydrate is used. This method provides the p-toluenesulfonic acid salt of the title compound which is converted to the oily title compound by distribution between dilute sodium hydroxide and ether. The organic phase is washed with saturated aqueous brine, dried over sodium sulfate, and filtered. Evaporation of the filtrate in vacuo leaves the title compound as a residual oil.
