Reaktionsschritte

9 g of the compound from Example 1 were suspended in 160 ml of tetrahydrofuran and 40 ml of ethanol, and 9 g of sodium carbonate were added. 5 g of decyl chloroformate, dissolved in 40 ml of tetrahydrofuran, are added dropwise to this suspension in the course of 20 minutes. When the reaction has ended, the batch is filtered and the residue on the filter is rinsed with tetrahydrofuran. The filtrate is combined with the wash solutions and evaporated in vacuo. The resulting syrup is purified by chromatography (mobile phase methylene chloride/methanol, 20:1)
