Synthetic Route of 41253-21-8, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 41253-21-8 name is Sodium 1,2,4-triazol-1-ide, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
Compound 271Synthesis of N-(5-(1H-1,2,4-triazol-1-yl)-2-(3,4,5-trimethoxybenzoyl)phenyl)acetamide; As shown in Reaction 1, first, magnesium was added to 1-bromo-3,4,5-trimethoxybenzene as a starting material. Then, Compound (VII) derivative was added thereto to obtain a compound [N-(5-fluoro-2-(3,4,5-trimethoxybenzoyl)phenyl)acetamide. Thus obtained compound [N-(5-fluoro-2-(3,4,5-trimethoxybenzoyl)phenyl)acetamide] (36.2 mg, 0.1 mmol) was dissolved in DMF (2 ml), and 1,2,4-triazole.Na (28.5 mg) was added thereto at room temperature. The mixture was heated with stirring for 2 hours. After completion of the reaction, the reaction mixture was cooled to room temperature and diluted with an EtOAc solution. The organic layer was washed with water, and brine. The extracted organic layer was dried over anhydrous MgSO4, and the solid substance was filtered off. The remaining solvent was removed by vacuum evaporation. The resulting residue was purified by column chromatography (SiO2, n-Hex/EA=2/1?1/1) to obtain Compound 271 (25.6 mg, 65%).1H NMR (CDCl3) delta 10.812 (s, 1H), 9.077 (s, 1H), 8.788 (s, 1H), 8.144 (s, 1H), 7.767 (d, J=8.36 Hz, 1H), 7.564 (d, J=8.52 Hz, 1H), 6.956 (s, 2H), 3.954 (s, 3H), 3.879 (s, 6H), 2.264 (s, 3H). MS (ESI) m/z 397 (M++H).
At the same time, in my other blogs, there are other synthetic methods of this type of compound, Sodium 1,2,4-triazol-1-ide, and friends who are interested can also refer to it.
