Procedure

5,6-difluoro-indan-1-one (2.49 g, 14.8 mmol) and piperidine (4.4 ml, 3.78 g, 44.4 mmol) were dissolved in pyridine (10 ml) and heated to reflux for 16 hours. The reaction was cooled, and the solvent removed under vacuum. The residue was taken in ethyl ether, washed with 1N aqueous sodium hydroxide and water, dried with magnesium sulfate, and the solvent removed under vacuum to give the desired product as 2.97 g of a black solid that was used without further purification. 1H NMR (300 MHz, CDCl3) 7.32 (d, 1H), 6.88 (d, 1H), 3.19 (m, 4H), 3.03 (m, 2H), 2.66 (m, 2H), 1.73 (m, 4H), 1.62 (m, 2H).
