Electric Literature of 956317-36-5, New discoveries in chemical research and development in 2021. We’ll be discussing some of the latest developments in chemical about CAS: 956317-36-5, name is 5-Methyl-2-(2H-1,2,3-triazol-2-yl)benzoic acid, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
To a suspension of 5-methyl-2-{2H-1,2,3-triazol-2-yl)benzoic acid (4.00 g, 19.7 mmol) in CH2CI2 (90 mL) cooled at 0 C was added DMF (76 mu, 0.98 mmol) and oxalyl chloride (2.15 mL, 24.6 mmol). The reaction was allowed to warm to ambient temperature and stirred for 3.5 h. The solution was concentrated in vacuo to provide 5-methyl-2-(2H-1,2,3- triazol-2-yl)benzoyl chloride as a yellow-orange oil which gave a mass ion (ES+) of 218.2. NMR 6 (ppm) (CDC13): 7.89 (2 H, s), 7.76 (1 H, d, J= 8.2 Hz), 7.59-7.60 (1 H, m), 7.48-7.50 (1 H, m), 2.48 (3 H, s).
The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules.Read on for other articles about 5-Methyl-2-(2H-1,2,3-triazol-2-yl)benzoic acid, hurry up and to see.
