Abstract
Process for the preparation of pyridine derivatives, more specifically N-alkyl-carbamates of 2,6-di (hydroxymethyl) pyridine, of the general formula ** (see formula) ** Wherein r represents hydrogen, or a methyl or ethyl group, characterized in that, in a first phase, phosgene is reacted, at low temperature and in an inert organic solvent medium, with 2,6-di (hydroxymethyl) pyridine, according to scheme ** (see formula) ** And, the obtained chloroformate is treated, in a second phase of the process, with ammonia or amines of the general formula r-nh2, where r has the same meaning expressed above, according to the equation (see formula) (Machine-translation by Google Translate, not legally binding)
