New discoveries in chemical research and development in 2021. The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 13273-53-5, name is 4-Bromo-1-methyl-1H-1,2,3-triazole belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. Quality Control of 4-Bromo-1-methyl-1H-1,2,3-triazole
Step 5 To the above solution was added 4-bromo-1-methyl-1H-1,2,3-triazole (XXXII) (0.064 g, 0.395 mmol), Pd(dppf)Cl2-CH2Cl2 adduct (0.032 g, 0.040 mmol) and 2 M aqueous solution of potassium carbonate (0.395 mL, 0.790 mmol). The reaction mixture was heated overnight at 95 C. The reaction mixture was absorbed on silica and purified by ISCO using CHCl3/7N NH3 in MeOH (0?5%) followed by preparative TLC to obtain N-(6-(1-methyl-1H-1,2,3-triazol-4-yl)isoquinolin-3-yl)-1-(3,3,3-trifluoropropyl) piperidine-4-carboxamide (271) as a beige solid (0.011 g, 0.025 mmol, 6.44% yield). 1H NMR (DMSO-d6, 500 MHz) delta ppm 1.60-1.73 (m, 2H), 1.76-1.84 (m, 2H), 1.92-2.01 (m, 2H), 2.41-2.60 (m, 5H), 2.94 (br d, J=11.25 Hz, 2 H), 4.14 (s, 3H), 8.01 (dd, J=8.51, 1.37 Hz, 1H), 8.11 (d, J=8.51 Hz, 1H), 8.28 (s, 1H), 8.50 (s, 1H), 8.73 (s, 1H), 9.11 (s, 1H), 10.55 (s, 1H); ESIMS found for C21H23F3N6O m/z 433.2 (M+1).
We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 4-Bromo-1-methyl-1H-1,2,3-triazole ,and how the biochemistry of the body works.
