Reaktionsschritte
A mixture of 100 g succinic anhydride, 100 g cis-3-hexen-1-ol, 88.5 ml pyridine and 7.3 g dimethylaminopyridine in 500 ml dichloromethane was refluxed for 4 hours. Ether was added and the mixture was acidified with HCl 2N then washed with brine. The organic layer was dried over magnesium sulfate and concentrated. The residue was distilled under vacuum to afford 185 g of product.
