A mild, catalyst-free synthesis of 2-aminopyridines
摘要:
Alkylation of 2-mercaptopyridine with 1,2-dibromoethane affords a cyclic dihydrothiazolopyridinium salt that can serve as a precursor of 2-aminopyridines. Its reaction with primary or secondary amines, either neat or in DMSO, under mild conditions gives the title compounds. (C) 2008 Elsevier Ltd. All rights reserved.
