Reaction mixture was heated at 80C for 16 hours and was then cooled to room temperature, diluted with ethyl acetate, washed with water and brine, dried over sodium sulfate and concentrated under reduced pressure. Crude material was purified by combiflash chromatography eluting at 0 1% methanol in dichlorometha e to afford l~(l-benzyl~4- piperidyl)pyrazole-4-carbaldehyde 46-4 (650 mg, 2.41 mmol, 70.42% yield) as brown gum.
