| titleOfInvention | Method for preparing n-($g(v)-bromoalkyl)phthalimides |
| abstract | The invention concerns a procedure for preparation of N-(ω-bromoalkyl)phthalimides which consists of reacting potassium phthalimide with an α,ω-dibromoalkane without cosolvent, at a temperature from 50° C. to 130° C. by using a molar ratio of α,ω-dibromoalkane to potassium phthalimide from 2.5 to 6, then of removing excess α,ω-dibromoalkane, under reduced pressure at a temperature equal to 150° C. at most, of taking up the reaction medium again with a low boiling point alcohol at a temperature near that of the boiling point of said alcohol, of filtering at this temperature, of cooling the filtrate obtained and then of recovering the N-(ω-bromoalkyl)phthalimide. |
