Microwave-assisted synthesis of 2-aminopyrimidines from silica gel-adsorbed propargyl alcohols and guanidine
A novel methodology toward the synthesis of 2-aminopyrimidines has been developed. The silica gel adsorbed propargyl alcohols and guanidine easilygive the corresponding 2-aminopyrimidines under microwave irradiation.
