Process for preparing pyrrolidinium salt |
| abstract |
The present application relates to a two-step process for the preparation of compounds of formula (I) in the form of salts or zwitterions. This method minimizes the relative proportional variation of diastereomers. <Formula I> In the above formula, R 1 and R 2 are each independently C 3 -C 8 -cycloalkyl or C 6 -C 10 -aryl, and R 3 and R 4 are each independently C 1 -C 8 -alkyl. |
