Adding a certain compound to certain chemical reactions, such as: 486460-21-3, name is 3-(Trifluoromethyl)-5,6,7,8-tetrahydro-[1,2,4]triazolo[4,3-a]pyrazine, belongs to pyrazines compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 486460-21-3, Recommanded Product: 3-(Trifluoromethyl)-5,6,7,8-tetrahydro-[1,2,4]triazolo[4,3-a]pyrazine
Example 1 : Preparation of (S)-benzyl 1-hydroxy-4-oxo-4-(3-(trifluoromethyl)- 5,6-dihydro-ri ,2,41triazolor4,3-aipyrazin-7(8H)-yl)butan-2-ylcarbamate A 2.0 M solution of AIMe3 in hexanes (0.98 ml_, 1.96 mmol) was added to a solution of 3-(trifluoromethyl)-5,6,7,8-tetrahydro-[1 ,2,4]triazolo[4,3-a]pyrazine (271 mg, 1.41 mmol) in anhydrous methylene chloride (5 ml_). The resulting mixture was added dropwise to a solution of (S)-benzyl 5-oxotetrahydrofuran- 3-ylcarbamate (265 mg, 1.13 mmol) in anhydrous methylene chloride (5 ml_) at 0 0C. When the reaction was completed, 1 M KHSO4 solution (25 ml_) was added slowly. The layers were separated and the aqueous layer was extracted with methylene chloride (25 ml_). The organic layers were mixed, dried over anhydrous Na2SO4, filtered and concentrated to dryness to yield (S)-benzyl 1 -hydroxy-4-oxo-4-(3-(trifluoromethyl)-5,6-dihydro- [1 ,2,4]triazolo[4,3-a] pyrazin-7(8H)-yl)butan-2-ylcarbamate (353 mg, 0.83 mmol, 73% yield).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 3-(Trifluoromethyl)-5,6,7,8-tetrahydro-[1,2,4]triazolo[4,3-a]pyrazine, other downstream synthetic routes, hurry up and to see.
