Process for preparing 3,6-disubstituted imidazo[1,2-b]pyridazine derivatives |
| abstract |
The present invention provides an industrially useful new method for preparing 3,6-disubstituted imidazo[1,2-b]pyridazine derivatives. The present invention provides a method for the preparation of 3,6-disubstituted imidazo[1,2-b]pyridazine derivatives using 6-fluoroimidazo[1,2-b]pyridazine as a starting material, A C-H activated aromatic substitution reaction with palladium was used. |
