Abstract

1. Procedimiento para preparar derivados del cornezuelo del centeno, de fórmula I, **(fórmula 01)** en donde cada una de R1 y R2 es hidrógeno o alquilo de 1 a 4 átomos de carbono, o R1 y R2, juntas, forman una cadena alquilidénica de 2 a 5 átomos de carbono, R3 es alquilo de 1 a 4 átomos de carbono, y R4 es hidrógeno, alquilo de 1 a 4 átomos de carbono, alquilo de 1 a 4 átomos de carbono substituído por 1 a 3 átomos de halógeno, con la condición de que el átomo de carbono alfa no lleve un halógeno, o alcoximetilo de 2 a 5 átomos de carbono, y sus sales de adición de ácido, caracterizado porque se reduce selectivamente en la posición 2, 3 un compuesto de fórmula II, **(fórmula 02)** en donde R1 a R4 tienen los significados previamente indicados, en presencia de un disolvente, a temperaturas entre 0 y + 40ºC aproximadamente, y, si se desea, se convierten los compuestos de fórmula I resultantes en sus sales de adición de ácido.1. Procedure for preparing ergot derivatives of formula I, **(formula 01)** wherein each of R1 and R2 is hydrogen or alkyl of 1 to 4 carbon atoms, or R1 and R2 together, form an alkylidene chain of 2 to 5 carbon atoms, R3 is alkyl of 1 to 4 carbon atoms, and R4 is hydrogen, alkyl of 1 to 4 carbon atoms, alkyl of 1 to 4 carbon atoms substituted by 1 to 3 halogen atoms, provided that the alpha carbon atom does not carry a halogen, or C2-C5-alkoxymethyl, and their acid addition salts, characterized in that a compound is selectively reduced in the 2,3-position of formula II, **(formula 02)** in which R1 to R4 have the previously indicated meanings, in the presence of a solvent, at temperatures between approximately 0 and +40°C, and, if desired, the compounds of formula II are converted I resulting in their acid addition salts.
