A series of 2,4-diamino-5-aryl-6-ethylpyrimidines embracing basic substituents in the 5-aryl ring was synthesized and evaluated for inhibitory activity against rat liver dihydrofolate reductase (DHFR). Maximal enzyme inhibition was observed for compounds bearing a benzylamino (19) or N-alkylbenzylamino substituent (29 and 30) in the 4-position of the phenyl ring and a nitro group in the 3-position

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
