-
, (2021/07/01)
The invention provides a method for preparing a long aliphatic chain diacid derivative. The method comprises the following steps of: (1) carrying out a cyclization reaction on long aliphatic chain diacid, the long aliphatic chain diacid having a structure as shown in a formula (A); (2) reacting the long aliphatic chain diacid cyclization product with benzyl alcohol to obtain long aliphatic chain diacid monobenzyl ester; (3) carrying out an esterification reaction on the long aliphatic chain diacid monobenzyl ester and N-hydroxysuccinimide so as to obtain long aliphatic chain diacid succinimide benzyl ester; (4) carrying out a nucleophilic addition amidation reaction on the long aliphatic chain diacid succinimide benzyl ester and a compound as shown in a formula (B) to obtain a compound as shown in a formula (C); (5) carrying out an esterification reaction on the compound as shown in the formula (C) and N-hydroxysuccinimide again so as to obtain a compound as shown in a formula (D); and (6) carrying out a debenzylation reaction on the compound shown in the formula (D) so as to obtain a compound shown in a formula (E).
