NEW AMINOPYRIMIDINONIC DERIVATIVES WITH POTENTIAL BIOLOGICAL ACTIVITY

In the industrial synthesis of fungicide, ethyrimol (I) (5-butyl-2-ethylamino-6-methyl-4-pyrimidinol), starting from ethylguanidine nitrate and butylacetoacetic ester, a by product (15 percent of the main product) was also formed: the 2-amino-5-butyl-3-ethyl-4-pyrimidinone (II). In order to render valuable this by-product by means of some of its potentially biologic active derivatives, its 2-amino function was used. By acylation with phenoxyacetyl chlorides, tosyl chloride, p-acetylaminobenzenesulfonic chloride, the corresponding amides were obtained. The amino function was also replaced by the hydroxyl and chlorine groups. With phosgene the N,N-disubstituted urea was obtained. The new compounds were characterized by means of 1H-NMR and IR spectra, some of them proving a biological activity.
