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. 1010120-55-4, name is 5-Bromo[1,2,4]triazolo[1,5-a]pyridin-2-amine, the common compound, a new synthetic route is introduced below. Safety of 5-Bromo[1,2,4]triazolo[1,5-a]pyridin-2-amine
4-[ 4-( 4,4,5,5-Tetramethyl-[1 ,3,2]dioxaborolan-2-yl)-benzyl]-thiomorpholine-1, 1-dioxide(1.1eq.) was added to a solution of 5-bromo-[1,2,4]triazolo[1,5-a]pyrid in-2-ylamine (4:1). K2C03 (2eq.) and PdCbdppf (0.03 eq.) were added to the solution. The resulting mixture was then heated in anoil bath at 90C for 16h under N 2. Water was added and the solution was extracted with ethyl acetate.The organic layers were dried over anhydrous MgS04 and evaporated in vacuo. The final compoundwas obtained after purification by flash chromatography.[00162] 1H (400 MHz, CDCh) 8 7.94-7.92 (d, 2H), 7.52-7.48 (m, 3H), 7.37-7.34 (m, 1H), 7.02-7.00(m, 1H), 6.00 (d, 2H), 3.76 (d, 2H), 3.15-3.13 (m, 4H), 2.93-2.91 (m, 4H).[00163] m/z 358.2 (M+H+, 100%).
The synthetic route of 1010120-55-4 has been constantly updated, and we look forward to future research findings.
