Versuchsvorschrift

4-{4-[(pyridin-2-ylamino)methyl]tetrahydro-2H-pyran-4-yl}phenol (200 mg, 0.704 mmol), 3-chloropropylpiperidine hydrochloride (152 mg, 0.775 mmol) and potassium carbonate (204 mg, 1.48 mmol) were stirred in DMF (1 ml) at 45° C. for 24 hours until complete. The reaction was then partitioned between ethyl acetate (40 ml) and water (40 ml). The organic layer was separated, dried over sodium sulphate and concentrated in vacuo to give a solid. The solid was purified by preparative HPLC to give the title compound (220 mg, 76%) as a white solid. 1H NMR (400 MHz, CDCl3) δ 1.44-1.55 (m, 2H), 1.64-1.78 (m, 4H), 1.85-2.00 (m, 2H), 2.08-2.18 (m, 4H), 2.52-2.70 (m, 6H), 3.48 (d, 2H), 3.52-3.62 (m, 2H), 3.78-3.85 (m, 2H), 4.02 (t, 2H), 6.21 (d, 1H), 6.50 (t, 1H), 6.90 (d, 2H), 7.24 (d, 2H), 7.34 (t, 1H), 8.01 (d, 1H). LRMS APCI+ m/z 410 [MH]+.
