   OtroPurify the reaction mixture by ion exchange chromatography (SCX resin, methanol→2 M ammonia/methanol) and silica gel chromatography (15:1→10:1 ethyl acetate:methanol)

Procedimiento

Combine 6-(4-Piperidin-3-yl-phenoxy)-nicotinamide (free base compound of example 322) (0.0255 g, 0.0858 mmol), 1-bromo-2-cyclohexylethane (0.0150 mL, 0.0958 mmol), and potassium carbonate (0.0245 g, 0.177 mmol) in dimethylformamide (1.0 mL) and stir for 10 min. Purify the reaction mixture by ion exchange chromatography (SCX resin, methanol→2 M ammonia/methanol) and silica gel chromatography (15:1→10:1 ethyl acetate:methanol) to provide 0.0146 g (42%) of the title compound as an off-white foam: high resolution mass spectrum (electrospray): m/z calc for C25H34N3O2 408.2651, found 408.2661; 1H NMR (methanol-d4): 8.61 (s br, 1H), 8.28 (d, 1H, J=7.8 Hz), 7.36 (d, 2H, J=7.8 Hz), 7.12 (d, 2H, J=7.8 Hz), 7.01 (d, 1H, J=8.3 Hz), 3.07 (d, 2H, J=10.2 Hz), 2.89 (t, 1H, J=11.2 Hz), 2.55-2.42 (m, 2H), 2.15-1.93 (m, 4H), 1.93-1.64 (m, 8H), 1.63-1.43 (m, 4H), 1.40-1.15 (m, 8H), 1.07-0.86 (m, 3H).
