International Classification:
C07D48704
US Classification:
544263
Abstract:
2-Amino-5, 8-dimethoxy[1,2,4]triazolo[1,5-c]-pyrimidine is prepared from a 5-chloro or 5-methoxy substituted 3-amino-8-methoxy[1,2,4]triazolo[4,3-c]-pyrimidine by reaction with methoxide in an alcohol solvent. Both rearrangement and, when the 5-substituent is chloro, methoxy substitution can be accomplished directly.

Dow AgroSciences LLC - Indianapolis IN
International Classification:
C07C 4122
US Classification:
568630, 568649, 568655
Abstract:
3-Substituted benzotrifluorides are selectively deprotonated and functionalized in the 2-position. The selectivity is achieved by equilibrating the mixture of lithiobenzotrifluorides initially formed in the presence of a primary or secondary amine catalyst.
