Abstract
The present invention relates to a process for the preparation of a N-(N'-substituted glycyl)-2-cyanopyrrolidine comprising at least (a) reacting, in the presence of dimethylformamide, a compound of formula (V) wherein, independently of each other, X1 and X3 are halogen; X2 is halogen, OH, O-C(=O)-CH2X3, -O-SO2-(C1-8)alkyl or -O-SO2-(aryl), with L-prolinamide, followed by (b) reacting the resultant compound without isolation with a dehydration agent, optionally followed by (c) reacting, in the presence of a base, the resultant compound without isolation with an appropriate amine and (d) recovering the resultant cornpound in free form or in acid addition salt form.
