Reaktionsschritte

In 0.4 ml of anhydrous dimethyl formamide was dissolved 1,14-tetradecanedioic acid monobenzyl ester (100 mg, 0.29 mmole). To the obtained solution were added sodium N-hydroxysulfosuccinimide (63 mg, 0.29 mmole) and a solution of DCC (65 mg, 0.29 mmole) in 0.4 ml of anhydrous dimethylformamide and the resulting mixture was stirred for 14 hours at a room temperature. The reaction mixture was filtered and the filtrate was stirred for 2 hours at a temperature under ice cooling. The solid that formed was collected by filtration and dried under reduced pressure to give N-(13-benzyloxycarbonyltridecanoyloxy)sulfosuccinimide sodium salt (66 mg, 42%) having the following properties.
