摘要
8-Aminopyridines la-e and 1-aminoisoquinoline with 1-chloromethylbenzotriazole give 2-amino-1-[alpha -benzotriazol-1-ylmethyl]pyridinium chlorides 2a-c and 1-amino-2-(alpha -benzotriazol-1-ylmethyl)isoquinolinium chloride 12, respectively. Compounds 2a-c and 12 react with aryl aldehydes 3a-h to afford imidazolo [1,2-a]pyridines 7a-k and imidazolo[2,1-a] isoquinolines 13a,b in good yields.
