This invention relates to novel compounds of the formula
wherein
X₁ and X₂ are each independently hydrogen or halogen with the proviso that at least one of X₁ and X₂ is a halogen atom,
A₁ and A₂ are each independently hydrogen, halogen or hydroxy with the provisos that where A₁ is hydroxy, A₂ is hydrogen, and where A₂ is hydroxy, A₁ is hydrogen,
Y₁ is nitrogen, a CH group, a CCl group, a CBr group or a CNH₂ group,
Y₂ is nitrogen or a CH group, and
Z is hydrogen, halogen, or NH₂,
which are useful as antiprotozoal agents.
