| titleOfInvention | A kind of naphthoquine phosphate process impurity and synthesis method thereof |
| abstract | The invention discloses the structure of an unreported naphtholquine phosphate process impurity represented by formula (I), and provides an alkylaminomethylphenol converted into a corresponding alkyloxymethylphenol, or a The method for converting alkylaminomethylphenol into substituted alkyloxymethylphenol, dissolving alkylaminomethylphenol or substituted alkylaminomethylphenol in alcohol and reacting with dihalogenated hydrocarbon and bicarbonate , using the ring-forming mechanism of quaternary ammonium salt and the good leaving property of quaternary ammonium group to prepare alkyloxymethylphenol or substituted alkyloxymethylphenol. The method does not need to use a special reactor, does not need to protect the phenolic hydroxyl group in the substrate, is simple to operate, uses simple and easy-to-obtain reagents, greatly shortens the reaction steps, and has high application value. |
