Abstract
A process for the preparation of dihydroxypyrimidine derivatives of the general formula: ##STR1## in which R.sup.1 and R.sup.2 are identical or different and are a hydrogen atom, aryl group, or a C.sub.1 -C.sub.4 -alkyl group or an aryl group, starting from a compound of the general formula: ##STR2## in which R.sup.2 has the meaning mentioned above and R.sup.3 is --CN or COOR.sup.4, in which R.sup.4 is a C.sub.1 -C.sub.4 -alkyl group.
