Definitions
- the present invention is a process for the preparation of compounds of general formula I.
- R 1 and R 2 are as defined in claim 1, their pharmaceutically acceptable salts and the solvates thereof.
- the present invention relates to a technical process for the preparation of compounds of the general formula I which possess CGRP-antagonistic properties. Furthermore, the invention relates to the compounds of general formulas V and VI per se, since they are particularly suitable for the preparation of the compounds of general formula I.
- the compounds of the general formulas V and VI are valuable starting materials for the synthesis of the compounds of general formula I which possess CGRP-antagonistic properties.
- the isolated intermediates are obtained as crystalline solids, which is for the purification and the separation of any resulting enantiomeric mixtures of great advantage.
- a first subject of the present invention relates to a process for the preparation of compounds of general formula I.
- R 1 is H, ds-alkyl, C (O) -O-benzyl, C (O) -O-te / f-butyl or benzyl, preferably H or benzyl, and
