PROCESS FOR THE PREPARATION OF PIRROLIDIN SALTS. |
| abstract |
A two-step process for the preparation of a compound of formula 1: (see formula (I)) in a salt or zwitterionic form, wherein R1 and R2 are each independently cycloalkyl of 3 to 8 carbon atoms, or aryl of 6 to 10 carbon atoms; and R3 and R4 are each independently alkyl of 1 to 8 carbon atoms. The process minimizes the variation in the relative proportions of the diastereoisomers. |
