Abstract
ABSTRACT Substituted amidines (1,2) where prepared from the condensation of benzyl, furfuryl alcohols and ethyl sulphate with thiourea. Chalcone compounds (3,5a and 5b) where also prepared from condensation of 4-nitrobenzaldehyde to give compound (3) while acetophenone, 4-hydroxy benzaldehyde and 1,3-dibromopropane gave the diformyl intermediate (4) then it was underwent further reaction with either acetophenone or 4-methyl acetophenone to afford compounds (5a,5b) respectively. Condensation of the above amidines with the resulted chalcones or dichalcones afforded the substituted pyrimidines (6-11). Their structures confirmation were studied by IR and were discussed.
