Condensation of
1,3-diaryl-5-chloroacetyl-4,6-dioxo-2-thioxoperhydropyrimidines
(2aâf) with 2-aminobenzenethiol in ethanol in the presence
of pyridine gives the title compounds (3aâf), under both
microwave irradiation and classical conditions; reactions are
ca. 180 times faster using the microwave rather than the
classical method.
