Process for preparing pyridine-substituted amino ketal derivatives |
| abstract |
The present invention relates to an efficient process for preparing derivatives of 1-(pyridinyl)-1,1-dialkoxy-2-aminoethane of the formula (I), with which compounds of the formula (I) can be prepared in high purity and yield and in the form of the free base without isolating the acetylpyridine oxime of the formula (XI) which is a critical product from a safety point of view as a solid. |
