In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 762240-92-6, name is 3-(Trifluoromethyl)-5,6,7,8-tetrahydro-[1,2,4]triazolo[4,3-a]pyrazine hydrochloride belongs to pyrazines compound, it is a common compound, a new synthetic route is introduced below. Quality Control of 3-(Trifluoromethyl)-5,6,7,8-tetrahydro-[1,2,4]triazolo[4,3-a]pyrazine hydrochloride
General procedure: A solution of 3-(trifluoromethyl)-5,6,7,8-tetrahydro [1,2,4]triazolo[4,3-a]pyrazine hydrochloride salt (1.0 eq.) in dimethylformamide(DMF, 2-3 mL)was added potassium carbonate (2.5eq.) at and stirred for 15 min at room temperature. To this, N-(benzo[d]thiazol-2-yl)-2-chloroacetamide derivatives (1.0 eq.) in DMF was added to the reaction mixture at room temperature. The resulting reaction mixturewas heated at 70 C for 18 h. The completion of the reaction was monitored on TLC (using 10% MeOH: DCM and ammonia as a modifier as mobile phase) which confirmed that the reaction got completed after 18 h. The reaction mixture was pouredinto ice-cold water and extracted with ethyl acetate (2 x 30 mL).Organic layers were combined and the combined organic layer was dried over sodium sulfate and concentrated under reduced pressure to afford crude desired product and crystallized it from methanol to get N-(benzo[d]thiazol-2-yl)-2-(3-(trifluoromethyl)-5,6-dihydro-[1,2,4]triazolo [4,3-a]pyrazin-7 (8H)-yl)acetamide derivatives(12a-12e) in good practical yield.
The synthetic route of 762240-92-6 has been constantly updated, and we look forward to future research findings.
