Rapid nucleophilic displacement reactions of 2-chloropyrimidine, 2-bromopyrimidine, 5-bromopyrimidine and chloropyrazine with nucleophiles under microwave irradiation was complete within several minutes with yields up to 99%. The method using microwave irradiation is superior to the classical heating processes. (C) 2002 Elsevier Science Ltd. All rights reserved.
