摘要：

Claisen condensation of 5-acetyl-1, 3-diaryl-1, 3-diaryl-1, 3-dihydro-6-hydroxy-4-oxo-2-thioxopyrimidines (1a-f) with ethyl acetate affords 1, 3-diaryl-1, 3-dihydro-6-hydroxy-4-oxo-5-(1, 3-dioxobutyl)-2-thioxopyrimidines (2a-f) which on heating in glacial acetic acid in the presence of phosphorus pentoxide furnish the title compounds (3a-f).
