ABSTRACT:
Improved processes for producing purine derivatives, such as 9-(2-chloro-6-fluorobenzyl)-6-methylaminopurine, which are useful as anticoccidial agents, and new arylazopyrimidine compounds of the formula: ##STR1## wherein R.sup.1 and R.sup.2 each is hydrogen, C.sub.1-3 alkyl, allyl or dihalobenzyl, and when either one of R.sup.1 and R.sup.2 is hydrogen, the other is other than hydrogen, and R.sup.3 is aryl, and acid addition salts thereof, which are useful as intermediates for production of the purine derivatives.
