Versuchsvorschrift
To a solution of ethyl (2E)-3-(5-chloro-2-pyrazinyl)acrylate (500 mg) in DMF (5 mL) was added (3R)-1-(4-chlorobenzoyl)-3-pyrrolidinamine (951 mg) and Et3N (1.15 mL). After stirring for 3 hours at 120° C., the reaction mixture was partitioned between ethyl acetate and H2O. The organic layer was washed with H2O, dried over MgSO4, filtered, and evaporated in vacuo. The residue was purified by column chromatography on silica gel to give ethyl (2E)-3-(5-{[(3R)-1-(4-chlorobenzoyl)-3-pyrrolidinyl]amino}-2-pyrazinyl)acrylate (601 mg).
