l-Amino-5-benzoyl-4-phenyl-lH-pyrimidine-2-thione (1) reacts with various carboxylic anhydrides (2a-e) under different conditions and gives the new amide and imide derivatives. Reaction of (1) with maleic anhydride (2b) resulted in acid derivative (3b). The structures of these compounds (3a-f) were determined by H-1 NMR, C-13 NMR, IR spectra and elemental analysis.
