A series of 2,4-diamino-5-(azidoaryl)-6-alkylpyrimidines has been prepared. The azide (36)(MZP) can be reduced by thiol reagents to the corresponding amine (28) but reductive deazidation occurred when the series of azidophenyl derivatives was heated with hydrazine hydrate. Degradation of azide (36) in a trifluoroacetic acid–trifluoromethanesulphonic acid mixture at 0 °C affords a means of introducing
