Brief introduction of 14529-54-5

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. 14529-54-5, 3,5-Dibromo-1-methylpyridin-2(1H)-one, other downstream synthetic routes, hurry up and to see.

Reference of 14529-54-5, Adding some certain compound to certain chemical reactions, such as: 14529-54-5, name is 3,5-Dibromo-1-methylpyridin-2(1H)-one,molecular formula is C6H5Br2NO, 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 14529-54-5.

Example 304c 5-Bromo-3-(5-(2-methoxyethyl)-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrazin-2-ylamino)-1-methylpyridin-2(1H)-one 304c A 100-mL round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with 304b (230 mg, 1.17 mmol), 3,5-dibromo-1-methylpyridin-2(1H)-one (468.4 mg, 1.76 mmol), Pd2(dba)3 (53.5 mg, 0.0585 mmol), Xantphos (67.6 mg, 0.117 mmol), Cs2CO3 (762.8 mg, 2.34 mmol), and dioxane (20 mL). After three cycles of vacuum/N2 flush, the mixture was heated at 100C for 3 h. Analysis of the reaction mixture by LCMS showed complete conversion to the desired product. It was cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure. The residue was purified by silica-gel column chromatography eluting with 40:1 dichloromethane/methanol to afford 304c as a dark solid (380 mg, 85%). MS-ESI: [M+H]+ 382.2
