Process for the preparation of tubulin inhibitors |
| 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; R 2 is H or C 1 -C 3 alkyl; n is an integer of 2, 3 or 4; X is Cl or Br; R 3 and R 4 are each independently H or C 1 -C 3 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 atom or 0-1 sulfur atom and optionally substituted with R5; R5 is d-C3 alkyl; where the dotted line is a possible bond. |
