A process for the preparation of a compound of formula: ##STR1## wherein R is an amino, hydrocarbylamino or dihydrocarbylamino radical, the hydrocarbylamino and dihydrocarbylamino radicals being unsubstituted, or substituted in the hydrocarbyl moiety with atoms or radicals which do not interfere with the process and Z is an acyl radical which comprises the steps of: (a) decarboxylating a compound of formula: ##STR2## to produce the corresponding 4-hydroxy-6-methyl-pyrimidine; and (B) TREATING THE CORRESPONDING 4-HYDROXY-6-METHYL PYRIMIDINE THUS PRODUCED WITH AN ACYLATING AGENT CAPABLE OF PROVIDING THE ACYL RADICAL Z; where both steps (a) and (b) are carried out in the same solvent or diluent.
