New downstream synthetic route of 875-66-1

This molecular description is the mechanism of the reaction; it describes how individual atoms, ions, or molecules interact to form particular products.If you are interested, you can also browse other articles of Cinnolin-4-ol, , We look forward to the emergence of more reaction modes in the future.

One of the major reasons is to use measurements of the macroscopic properties of a system, the rate of change in the concentration of reactants or products with time, to discover the sequence of events that occur at the molecular level. 875-66-1, introduce a new downstream synthesis route., 875-66-1

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.
