Abstract

Process for obtaining 2-methyl-3-hydroxy-4-ethylaminomethyl-5-methyloeroaptomethyl-pyridine and its acid addition salts, characterized in that a pyridine derivative of general formula II ** (See formula) ** where R means -CH = N-CH2- or -CH2-N = CH-, or a salt of a compound thereof is reacted with sodiumborohydride, in the presence of an inert solvent at temperatures between 0 and 50º or with zinc and a carboxylic acid or a mineral acid at temperatures between 20 and 100ºC or with hydrogen in the presence of Raney nickel and in an acid, neutral or basic zone in the presence of an inert solvent at temperatures between -20 and + 150ºC and pressures between 1 and 100 atmospheres.
