Process for the preparation of pyrimidine derivatives, of the general formula: ** (formula) ** in which a represents an alkylene or alkenylene group which, together with the carbon atoms of the pyridine nucleus to which it is attached, forms a ring homocyclic containing 5, 6 or 7 carbon atoms, which homocyclic ring can carry one or more substituents selected from halogen atoms and lower alkyl and lower alkoxy groups, the total number of carbon atoms of the alkyl substituents being not more than 8 and/or alkoxy, and r represents a dialkyl (lower) amino group, or a mononuclear, saturated or unsaturated heterocyclic group, containing nitrogen, oxygen or sulfur, linked to the pyrimidine ring through a carbon atom or, when the group contains a nitrogen atom, through the nitrogen atom or through a carbon atom, optionally carrying said heterocyclic group one or more halogen atoms or substituted lower alkyl or lower alkoxy and/or when it contains a nitrogen atom not directly linked to the pyrimidyl group, an N-acyl substituent.
