Related Products of 1280210-80-1, The chemical industry reduces the impact on the environment during synthesis 1280210-80-1, name is MK-3102 interMediate3, I believe this compound will play a more active role in future production and life.

Step A: tert-Butyl { (2R.3S,5R)-2-(2,5-difluorophenyl)-5- [2-(methylsulfonyl)-2,6- dihydropyrrolo [3 ,4-c]pyrazol-5(4H)-yl]tetrahydro-2H-pyran-3-yl } carbamateA vessel was charged with N,N-dimethylacetamide (520.6 kg), 2-(methylsulfonyl)-2,4,5,6-tetrahydropyrrolo[3,4-c]pyrazol-5-ium benzenesulfonate (intermediate 2, 30.0 kg, 86.8 mol), and tert-butyl [(2R,35)-2-(2,5-difluorophenyl)-5-oxotetrahydro-2H-pyran-3 -yl]carbamate (intermediate 1, 31.2 kg, 95.3 mol). After dissolving at room temperature, the solution was cooled to 0-10 C and sodium triacetoxyborohydride (24 kg, 113 mol) was added in four equalportions every 40 mm. The reaction was then allowed to warm to room temperature and stirred an additional 5h. The solution was then cooled to 5-15 C and water (672 kg) was added over 1- 2h. The resulting slurry was filtered and the cake washed sequentially with N,Ndimethylacetamide, twice with water, and then n-heptane. The solids were dried under vacuum at 40-60 C to give tert-butyl { (2R,3S,5R)-2-(2,5-difluorophenyl)-5 – [2-(methylsulfonyl)-2,6-dihydropyrrolo [3 ,4-cjpyrazol-5(41])-yljtetrahydro-2H-pyran-3-yl } carbamate.

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, MK-3102 interMediate3, other downstream synthetic routes, hurry up and to see.

Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 1280210-80-1, name is MK-3102 interMediate3, This compound has unique chemical properties. The synthetic route is as follows., name: MK-3102 interMediate3

To a solution of 11 (260 mg, 0.69 mmol) in DMAc (1 mL) was added Ml (288 mg, 0.84 mmol) followed by Ets (0.15 mL, 1.04 mmol) and stirred it for 5 minutes. AcOH (0.10 mL, 1.74 mmol) was added to the reaction mixture and continued the stirring for 30 minutes. NaBH(OAc)3 (0.44 g, 2.09 mmol) was added to the reaction mixture and continued the stirring for 2 days. The reaction mixture was quenched with NH4OH and extracted with EtOAc. Combined organics were concentrated under vacuum. Crude mixture was purified by silica gel chromatography afforded 12.
