Microwave-assisted synthesis of 4-amino-3,5-dihalopyridines
摘要:
4-Amino-3,5-dihalopyridines have been efficiently prepared via microwave-assisted nucleophilic aromatic substitution of 3,4,5-trihalopyridines using 1-1.1 equiv of primary and secondary amines. The reaction is also applicable to electron rich arylamines. (C) 2010 Elsevier Ltd. All rights reserved.
