実験手順

158 g of the above compound are dissolved in 1054 cm3 of methanol including 10% of water containing 129.1 g of potassium hydroxide. The reaction medium is brought to reflux for 6 hours and then filtered through paper while hot. The filtrate is made up with 300 cm3 of water and left at 4° C. overnight. The solid formed is isolated by filtration on a glass sinter. 145 g of 2-amino-3-hydroxyoctadecanol or dihydrosphingosine are thereby obtained in pure erythro form.
