実験手順
In a separate process, 23.9 g of azelaic monomethylester was dissolved in 30 ml chloroform. Oxalylchloride (15 ml) was added, all at once, and the mixture refluxed 2 hours at 50° C. The mixture was cooled; excess solvent and oxalylchloride were evaporated. After distillation, 25.8 g of CH3OCO(CH2)7COCl was obtained.
