The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. 423165-07-5, name is exo-3-(3-Isopropyl-5-methyl-4H-1,2,4-triazol-4-yl)-8-azabicyclo[3.2.1]octane, molecular formula is C13H22N4, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
Compound (I) (3.09 g) as prepared in Example 5, compound (II) (2.34 g) as prepared in Example 4, and THF (30 g) were mixed in a round bottom flask. After the mixture was cooled in an ice bath and reacted for 10 min, HOAc (1.5 g) was added into the mixture and reacted for another 10 min. Subsequently, NaBH(OAc)2 (3.2 g) was added into the reaction mixture to reduce intermediate to crude product. The whole reaction mixture was quenched with 15% NaOH to pH >10. The organic phase was collected by phase separation, and concentrated under reduced pressure. Maraviroc (4.6 g) in a form of white powder was obtained from the concentrate by crystallization with EA.
By the way, if you are interested in learning more fun chemistry with your kids, get your hands into one chemistry set now, and start enjoying the best part of chemistry: experiments about exo-3-(3-Isopropyl-5-methyl-4H-1,2,4-triazol-4-yl)-8-azabicyclo[3.2.1]octane.
