Versuchsvorschrift

(3,5-Dimethyl-pyridin-2-ylmethyl)-(3-isopropyl-pyridin-2-ylmethyl)-piperidin-4-yl-amine (125 mg, 0.36 mmol) and N-(phenoxycarbonyl)methoxylamine (120 mg, 0.71 mmol) were stirred in THF (3.5 mL) for 16 hours. The solvent was removed under reduced pressure and the residue purified by column chromatography with silica gel (20:1:0.2 CH2Cl2MeOH:NH4OH), COMPOUND 300 as a sticky solid (110 mg, 72%). 1H NMR (CDCl3) δ 0.93 (d, 6H, J=6.9 Hz), 1.62 (dq, 2H, J=12.3, 3.8 Hz), 1.89 (br d, 2H, J=12.3 Hz), 2.16 (s, 3H), 2.28 (s, 3H), 2.64 (br t, 2H, J=12.3 Hz), 2.74 (m, 1H), 2.78 (sept, 1H, J=6.9 Hz), 3.71 (s, 3H), 3.77 (s, 2H), 3.82 (s, 2H), 4.02 (br d, 2H, J=12.0 Hz), 7.13 (br, 1H(NH)), 7.16 (m, 1H), 7.24 (s, 1H), 7.50 (d, 1H, J=7.2 Hz), 8.18 (s, 1H), 8.32 (d, 1H, J=3.9 Hz). 13C NMR (CDCl3) δ 18.30, 18.45, 23.59 (2C), 27.30 (2C), 27.38, 44.40 (2C), 54.35 (2C), 57.24, 64.49, 123.20, 132.30, 133.23, 133.88, 139.09, 144.42, 146.05, 146.63, 154.42, 156.24, 159.06.
