| titleOfInvention | Process for the preparation of 2-(4-hydroxy-3-morfolynil)-2-cyclohexenone |
| abstract | It is disclosed a process for the preparation of 2-(4-hydroxy-3-morfolinyl)-2-cycloesenone (BTG-1675A) comprising the steps of: i) reacting N-hydroxymorpholine with cycloesanone in the presence of an oxidation agent thus obtaining an isoxazolidine of Formula IV; and ii) converting the isoxazolidine of Formula IV into 2-(4-hydroxy-3-morfolinyl)-2-cycloesenone. Advantageously, the oxidation agent of the step i) is selected from the group consisting of metal oxides, esters and amides of the azodicarboxylic acid and the step ii) of conversion is carried out by basic catalysis followed by trituration in an aromatic hydrocarbon, preferably toluene. The process disclosed allows to obtain BTG-1675A according to the invention in an amount of hundreds of grams and on an industrial scale. The invention further concerns a new process for preparing hydroxylamines, particularly N-hydroxymorpholine, which is used in the process for preparing BTG-1675A. |
