Versuchsvorschrift

Procedure EE: In a microwave reactor vessel, add (4-bromo-2-fluoro-phenyl)-(2-(S)-pyrrolidin-1-ylmethyl-pyrrolidin-yl)methanone (1.0 mmol), 4-methanesulfonylphenyl boronic acid (2.5 mmol), dichloropalladium di-triphenylphosphine (0.2 mmol), cesium fluoride (9.0 mmol) and acetonitrile (0.20M) and run in a CEM microwave reactor for 10 minutes at 120° C. with 75W power and cooling on. After this time, wash the reaction with water while extracting with 10% isopropanol/dichloromethane. Dry the organic layer with sodium sulfate, filter and concentrate in vacuo. Purify the title compound via radial chromatography eluting with 2M ammonia in methanol and dichloromethane. MS (m/e): 431.2 (M+1)
