This paper describes a facile and general synthesis of a new class of the hybrid compounds (4, 5 and 16), possessing 5-deazapteridine and steroid in the same ring system, by condensation of 6-(monosubstituted amino)uracils (9) or 6-(monosubstituted amino)-2-phenylpyrimidin-4(3H)-ones (14) with 2-hydroxy-methyleneandrostanolone (10) or 2-hydroxymethylenetestosterone (15) under heating in the presence of p-toluenesulfonic acid monohydrate and their potential unti-coccidiosis activities.
