| titleOfInvention | Process for the preparation of chloromethylpyridines |
| abstract | n für die Zahlen 0, 1, 2 oder 3 steht und X für Halogen steht, indem man Aminomethylpyridine der allgemeinen Formel (II)n n mit einem Nitrosierungsmittel bzw Diazotierungsmittel in Gegenwart eines Verdünnungsmittels und gegebenenfalls in Gegenwart von Hydrogenchlorid bei Temperaturen zwischen -20 o C und +50 o C umsetzt und dann auf übliche Weise aufarbeitet.The invention relates to a new process for the preparation of chloromethylpyridines of the general formula (I) in which n stands for the numbers 0, 1, 2 or 3 and X represents halogen, by using aminomethylpyridines of the general formula (II) with a nitrosating agent or diazotizing agent in the presence of a diluent and optionally in the presence of hydrogen chloride at temperatures between -20 o C and +50 o C and then worked up in the usual way. |
