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. 944709-42-6, name is 6,8-Dibromo-[1,2,4]triazolo[1,5-a]pyrazine, This compound has unique chemical properties. The synthetic route is as follows., Recommanded Product: 944709-42-6
A solution of (2-fluorobenzyl)zinc(II) chloride (18.0 ml, 0.5 M in THF, 9.00 mmol) was added to a mixture of PdCl2(PPh3)2 (0.253 g, 0.360 mmol) and commercially available intermediate Int-7a (2.00 g, 7.20 mmol). The reaction was purged with nitrogen, sealed and heated to 50 C for 1 h. The reaction mixture was cooled to room temperature and directly purified by silica gel chromatography utilizing a gradient of 0-70% ethyl acetate in hexanes to afford intermediate Int-7b (1.49 g, 61%). 1H NMR: (500 MHz, DMSO-d6), d (ppm): 9.46 (s, 1H), 8.74 (s, 1H), 7.39 – 7.42 (m, 1H), 7.30 – 7.34 (m, 1H), 7.14 – 7.21 (m, 2 H), 4.56 (s, 2H). MS ES+ m/z = 307.1 [M]+, 309.0 [M+2]+,
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 944709-42-6.
