Process for the preparation of 5-hydroxymethylthiazole

5-Hydroxymethylthiazole is prepared in an improved manner by reducing 5-formylthiazole using a borane compound. Particularly advantageous in this case is the use of 5-formylthiazole which has been obtained by reaction of a 2-halomalonaldehyde compound with thioformamide in the presence of less than...

description 5-Hydroxymethylthiazole is prepared in an improved manner by reducing 5-formylthiazole using a borane compound. Particularly advantageous in this case is the use of 5-formylthiazole which has been obtained by reaction of a 2-halomalonaldehyde compound with thioformamide in the presence of less than 5% by weight of water (based on the reaction mixture).
