A pyrimidine derivative of the formulae (Ia), (Ib) and (Ic), ##STR1## wherein R stands for an alkyl group group with 1 to 6 carbon atoms or an aryl group optionally substituted by halogen atom; and X stands for chlorine or bromine atom or an arylsulfonyloxy group optionally substituted by 1 to 3 lower alkyl groups. The subject pyrimidine derivatives are intermediates for preparing 6-amino-1,2-dihydro-1-hydroxy-2-imino-4-piperidinopyrimidine.
