Reaction Steps

A mixture of 1-benzyl-3-chloropiperidine (3.83 g, 18.3 mmol), 1H-pyrrolo[2,3-b]pyridine (4.4 g, 36.5 mmol) and cesium carbonate (17.8 g, 54.8 mmol) in DMSO is stirred at 80° C. under a nitrogen atmosphere for 24 h. The reaction is monitored by thin layer chromatography. Two additional amounts of 1-benzyl-3-chloro-piperidine (3.83 g and 1.91 g) are added at 12 h intervals. After 48 h, the mixture is cooled, treated with water and extracted with ethyl acetate. The extracts are combined, washed sequentially with water and brine and concentrated in vacuo. The resultant residue is purified by flash chromatography (4-5% methanol in CH2Cl2 as eluent) to afford the title compound as an oil, 6.5 g (60% yield), identified by HNMR and mass spectral analyses.
