Triazolo-pyrimidine derivs. of formula (Ia) and (Ib) are new. Q = H, a heterocyclic gp. opt. substd. by 1-4C alkyl and contg. 1 or more O and/or N, or -SR1 or -NR2R3; R1 = alkyl or aralkyl; R2 and R3 independently = H, alkyl, alkenyl, cycloalkyl, aralkyl, aryl or heterocyclic; m and n independently = 0-4; providing that if m = 0, then n is not 0, and if both m and n = 1 or m = 0 and n = 2, then Q is not methylthio or morpholino. |
