When developing chemical systems it’s of course important to gain a deep understanding of the chemical reaction process. 875-66-1. In an article, Which mentioned a new discovery about875-66-1 Name is Cinnolin-4-ol.
875-66-1, Example 20: Synthesis of 1- [4- (5-FLUORO-2-METHOXYPHENYL)-2-HYDROXY-4-METHYL-2- TRIFLUOROMETHYLPENTYL]-LH-CINNOLIN-4-ONE To a suspension of 2- [2- (5-fluoro-2-methoxyphenyl)-2-methylpropyl]-2-trifluoromethyloxirane (216 mg) and cinnolin-4-ol (V. G. Chapoulaud et AL., Tetrahedron, 2000,56, pp. 5499-5507) (216 mg) in anhydrous ethanol (1.2 ML) was added sodium ethoxide (21 wt. % solution in ethanol, 276 PL). After heating at 85C for 16 hours, the reaction mixture was diluted with ethyl acetate, dried over sodium sulfate, filtered, and concentrated in vacuo. The residue was purified by preparative TLC (eluted with 40% ethyl acetate-hexanes) to give the title compound as a pale yellow solid (26 mg), m. p. 122C-123C.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In the meantime we’ve collected together some recent articles in this area about 875-66-1 to whet your appetite. Happy reading! 875-66-1
