3'-bromo-2'-methylacetophenone Chemische Eigenschaften,Einsatz,Produktion Methoden
Synthese
To a stirred and refluxing Grignard-complex, previously prepared starting from 7.3 parts of magnesium, 52.6 parts of methyl iodide in 160 parts of ether, is added dropwise a solution of 19.6 parts of 3'-bromo-2'-methylbenzonitrile in 40 parts of ether. Upon completion, stirring at reflux is continued for 20 hours. The reaction mixture is cooled to 0 C and poured onto 500 parts of ice water while stirring vigorously. The ethereal phase is separated, dried and evaporated. The residue is boiled in 60 parts of a 6N hydrochloric acid solution for 10 minutes. The separated oil is extracted with ether. The extract is washed with water, dried and evaporated. The residue is distilled, yielding 3'-bromo-2'-methylacetophenone.
