Process and intermediates for the preparation of retigabine |
| abstract |
A method for the preparation of retigabine starting with intermediate III is disclosed, comprising the step of protecting the secondary amine of III with a protecting group followed by N-ethoxycarbonylation of the primary amino group of the product obtained. The preparation of retigabine is completed by steps comprising removal of the protecting group and reduction of the nitro group to amino, which can be performed in any order or simultaneously. Novel intermediates usable with said method are also described. |
