A process for the preparation of 5-hydroxymethylthiazole comprises reacting a compound of formula (A) with a carboxylic acid salt (optimally in the presence of a quaternary ammonium salt) and hydrolyzing the resulting ester. Subsequent dechlorination gives 5-hydroxymethylthiazole.
Procédé pour la préparation de 5-hydroxyméthylthiazole qui consiste à établir une réaction entre un composé de la formule (A) et un sel d'acide carboxylique (on réunira les conditions optimales en présence d'un sel d'ammonium quaternaire), et à hydrolyser l'ester résultant. La déchloration qui s'ensuit permet d'obtenir le 5-hydroxyméthylthiazole.
