Procedure

Cesium carbonate (100 mg) and 4-phenylpiperidine (48 mg) were added to a solution of (R)-2-chloro-N-[4-(3-dimethylaminopyrrolidin-1-yl)phenyl]acetamide (80 mg) in acetonitrile (5 ml) and DMF (1 ml), and the mixture was kept at 65° C. for 12 hours. The mixture was freed of volatile fractions and the residue was partitioned between water and dichloromethane. The organic phase was dried over sodium sulfate, filtered and concentrated. The residue was purified by chromatography (silica gel, eluent: methanol/dichloromethane). This resulted in the product with the molecular weight of 406.58 (C25H34N4O); MS (ESI): 407 (M+H+).
