Abstract
9-(2,6-Dihalobenzyl)adenines are prepared by allowing 2,6-dihalobenzyl halides to react with a salt of adenine in a solid-liquid or liquid-liquid two phase system in the presence of an onium salt phase transfer catalyst. The resulting compounds have anticoccidial activity and are useful in controlling cecal and/or intestinal coccidiosis when administered in minor quantities to animals, in particular to poultry usually in admixture with animal sustenance.
