| titleOfInvention | Process for the continuous production of intermediates for the production of 3-hydroxypyridine compounds |
| abstract | The present invention relates to a process for the continuous preparation of compounds of the formula I. in which R 1 represents hydrogen or optionally substituted alkyl and R 2 represents optionally substituted alkyl and R 3 , R 3 ' independently of one another represent hydroxyl protective groups which are optionally linked to one another, by continuously adding an oxazole compound of the general formula II and a protected 2-butene-1,4-diol of the general formula III to a reaction zone ; wherein R 1 , R 2 , R 3 and R 3 'have the meanings given above, in a molar ratio III: II of at least 1: 1 and continuously discharges from the reaction zone a product stream containing the compound I, the reaction zone as a system with low backmixing is designed. |
