Reaction Steps

To commercially available 4-chlorobenzonitrile 17 (1 g, 7.26 mmol) 3 ml of piperidine were added and the reaction was heated at 100° C. for 72 hours in closed vessel. The reaction was evaporated and the residue was dissolved in AcOEt and washed with water and brine. The purification of the crude residue by chromatographic column using AcOEt 1/Petroleum ether 9 as eluant gave 1.2 g of a pale yellow oil. Yield=89% 1HNMR (DMSO, 200 MHz) δ 1.57 (6H, m), 3.34 (4H, m), 6.98 (2H, d, J=9 Hz), 7.53 (2H, d, J=9 Hz)
