Versuchsvorschrift
A solution of ethyl (2E)-3-{5-chloro-6-[(3R)-3-pyrrolidinylamino]-3-pyridinyl}acrylate dihydrochloride (2.0 g) in H2O (10 ml) was adjusted to pH 8.5 With 20% K2CO3 solution and extracted with CHCl3. The extract was dried over MgSO4, the solvent was evaporated in vacuo to give ethyl (2E)-3-{5-chloro-6-[(3R)-3-pyrrolidinylamino]-3-pyridinyl}acrylate (1.47 g).
