| titleOfInvention | Method for producing photobleaching inhibitor |
| abstract | (57) [Summary] (Modified) [Object] To provide a method for easily and inexpensively producing a photobleaching inhibitor comprising a nitrogen-containing heterocyclic derivative having a branched long-chain alkyl group. [Structure] In the method for producing a photobleaching inhibitor represented by the following general formula [I], the crude product containing [I] is mixed with a protic acid in an organic solvent, and the produced protic acid salt is fractionated. , Then isolate [I] with base. [In the formula, R: a branched alkyl group having 8 or more carbon atoms; Z: 5 7-membered heterocyclic ring-forming non-metal atomic group; X 1 , X 2 : divalent linking group; Ar: aryl group; l, m, n: 0 or 1. The compound having the illustrated structure is a specific example of the photobleaching inhibitor of the general formula [I]. ] |
