The purity of the parent substance of (E)-N-(6,6-dimethylhept-2-en-4-ynyl)-N-methylnaphth-1-ylmethylamine (terbinafine) is evaluated via TLC identification of the main impurities appearing during its synthesis via alkylation of N-methylnaphth-1-ylmethylamine with 1-chloro-6,6-dimethyl-2-hept-2-en-4-yne The possible formation of impurities including N-methyl-N,N-di(methylnaphth-1-yl)amine, N-methylnaphth-1-ylmethylamine, N-methylnaphth-2-ylmethylamine, (E)-N-(6,6-dimethylhept-2-en-4-ynyl)-N-methylnaphth-1-ylmethylamine, (Z)-N-(6,6-dimethylhept-2-en-4-ynyl)-N-methylnaphth-1-ylmethylamine, (E)-N-(6,6-dimethylhept-2-en-4-ynyl)-N-methylnaphth-2-ylmethylamine, and (Z)-N-(6,6-dimethylhept-2-en-4-ynyl)-N-methylnaphth-2-ylmethylamine was confirmed by means of countersynthesis.
(E)-N-(6,6-二甲基庚-2-烯-4-炔基)-N-甲基萘-1-基甲基胺(特比萘芬)母体物质的纯度通过薄层色谱法鉴定其在合成过程中出现的主要杂质来评估,该合成过程是通过N-甲基萘-1-基甲基胺与1-氯-6,6-二甲基-2-庚-2-烯-4-炔的烷化反应进行的。通过反合成法确认了可能形成的杂质,包括N-甲基-N,N-二(甲基萘-1-基)胺、N-甲基萘-1-基甲基胺、N-甲基萘-2-基甲基胺、(E)-N-(6,6-二甲基庚-2-烯-4-炔基)-N-甲基萘-1-基甲基胺、(Z)-N-(6,6-二甲基庚-2-烯-4-炔基)-N-甲基萘-1-基甲基胺、(E)-N-(6,6-二甲基庚-2-烯-4-炔基)-N-甲基萘-2-基甲基胺和(Z)-N-(6,6-二甲基庚-2-烯-4-�
