Reference 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.
EXAMPLE B5-Fluoro-2-{r(3R,6R)-l-(2-iodo-5-methylben2oyl)-6-methylpiperidin-3-yllmethoxy}pyridine (B- To a solution of A£7 (325 mg, 1.5 mmol) in CH2CI2 (50 ml) at 0C was added diisopropylethylamine (506 mL, 2.9 mmol) followed by C-I (447 mg, 1.6 mmol, generated from A-8 by treatment with SOCI2 and catalytic DMF in CH2CI2). After warming to room temperature and stirring for 2 h, the reaction was partitioned between CH2CI2 and saturated aqueous NaHC03. The layers were separated, the aqueous was extracted again with CH2CI2, the combined organics were washed with water, dried over Na2SO4, filtered and concentrated. The crude material was purified by gradient elution on silica gel (0 to 100% EtOAc in Hex) to yield 530 mg of B1^aS a white solid. Data for B1^: LRMS m/z (M+H): 469.1.
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.
