Versuchsvorschrift

To a solution of (S)-isopropyl 7-cyano-1,2,3,4-tetrahydrocyclopenta[b]indol-2-ylcarbamate (680 mg, 2.40 mmol) and 4-chloro-2-(chloromethyl)-3-methoxypyridine (553 mg, 2.88 mmol) in dimethylformamide (5 mL) is added cesium carbonate (1.17 g, 3.60 mmol) and the mixture stirred at room temperature overnight. The reaction mixture is diluted with water and the beige solid is filtered. It is rinsed with water and then dried in a vacuum oven at 50° C. for 48 h to obtain a gray solid (970 mg, 92%). LC-ES/MS m/z 439.0 [M+H]+.
