Demethylation of 14-hydroxy substituted alkaloid derivatives |
| abstract |
The present invention is directed to a method for demethylating 14-hydroxy substituted alkaloid derivatives, in particular of 14-hydroxy-17-methyl-4,5- epoxymorphinane-6-on--derivatives. This is achieved by reacting a starting compound with a compound of general formula R1OOC-N=N-COOR2 in a suitable solvent. |
