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. 6863-74-7, name is 6-Chloropyrazine-2-carbonitrile belongs to pyrazines compound, it is a common compound, a new synthetic route is introduced below. 6863-74-7
A mixture of tert-butyl ((1R,4R,7R)-2-(1-(azetidin-3-ylmethyl)-2-(1- (cyclopropylmethyl)-1H-pyrrolo[2,3-b]pyridin-2-yl)-7-methoxy-1H-benzo[d]imidazole- 5-carbonyl)-2-azabicyclo[2.2.1]heptan-7-yl)carbamate (15 mg, 0.024 mmol), 6- chloropyrazine-2-carbonitrile (3.34 mg, 0.024 mmol), cesium carbonate (15.62 mg, 0.048 mmol), BINAP (0.746 mg, 1.199 mmol) and Pd2(dba)3 (1.098 mg, 1.199 mmol) in degassed dioxane (1.0 mL) under nitrogen in a seal vial was stirred at 90C for 18 hour. The mixture was diluted with EtOAc (5 mL) and was washed with a solution of aqueous saturated sodium bicarbonate (5 mL). The organic layer was dried over sodium sulfate and concentrated to give crude tert-butyl ((1R,4R,7R)-2-(1-(azetidin-3-ylmethyl)-2-(1- (cyclopropylmethyl)-1H-pyrrolo[2,3-b]pyridin-2-yl)-7-methoxy-1H-benzo[d]imidazole- 5-carbonyl)-2-azabicyclo[2.2.1]heptan-7-yl)carbamate (15 mg, 0.024 mmol). Material was used as is in next reaction.
The synthetic route of 6863-74-7 has been constantly updated, and we look forward to future research findings.
