Abstract:
In a first stage of a process for the preparation of 6-piperidino-2,4-diaminopyrimidine-3-oxide at least one of the two amino groups of a compound having formula (1): ##STR1## where X represents a halogen atom or OH group, is protected by an addition reaction with an isocyanate having formula:R--N=C=OIn this formula R represents an alkyl group, or one of the amino groups. The resulting urea derivative is then oxidized to produce the corresponding N-oxide which is then reacted with piperidine. The protective group(s) are then eliminated by reaction with an organic or inorganic base.
