Synthesis and anti‐HIV‐1 evaluation of 1,5‐disubstituted pyrimidine‐2,4‐diones

1,5-Disubstituted pyrimidine-2,4-diones were synthesized by fusion of 5-bromouracil with an aniline derivative followed by coupling with benzyl halide whereas the opposite synthesis sequence failed. Also 4,6-dichloro-N,N,5-trimethylpyrimidin-2-amine was treated with phenols. The products were tested for their activity against HIV-1.
