Procedure
To commercially available 2-fluoro-4-methylbenzonitrile 15b (2.5 g, 18.5 mmol) was added piperidine (4 equiv., 7.3 ml) and the solution was heated at 80° C. overnight. The reaction was evaporated and the residue was dissolved in AcOEt and washed with water and brine. The organic phase was evaporated obtaining 2.3 g of a white solid. Yield=65% 1HNMR (DMSO, 200 MHz) δ 1.62 (6H, m), 2.32 (3H, s), 3.07 (4H, m), 6.87 (1H, dd, J=7.8 Hz, J′=0.8 Hz), 6.95 (1H, s), 7.53 (1H, d, J=7.8 Hz)
