Abstract: The present invention provides a process for the preparation of 6-[(substituted)phenyl]-triazolopyrimidine dicarboxylic acid salt and as a hydrated salt having the structural formula (I) wherein: R1 is CF3 or C2F5; R2 is H or C1-C3 alkyl; n is an integer of 2, 3, or 4; X is Cl or Br; R3 and R4 are each independently H or C1-C3 alkyl; or R3 and R4 when optionally taken together with the nitrogen atom to which each is attached form a 4 to 6 membered saturated heterocyclic ring having 1-2 nitrogen atoms and 0-1 oxygen atoms or 0-1 sulfur atoms, and optionally substituted with R5; R5 is C1-C3 alkyl; wherein the dotted line is an optional bond.

Abstract: There is provided a process for the preparation of substituted amino alcohols HO—(CH2)n—NR1R2 from haloalcohols HO—(CH2)n—X, where X is Cl, Br or I, by reaction with an amine HNR1R2, in water as solvent at a temperature range of about 20° C. to about 90° C. optionally in the presence of a catalytic amount of an iodide source metal iodides. The haloalcohols are useful in the preparation of 6-[(substituted)phenyl]-triazolopyrimidine compounds which are useful in the treatment of cancer.
