Combine 6-(4-piperidin-3-yl-phenoxy)-nicotinamide (compound of example 322) (0.0237 g, 0.0797 mmol), (2-bromoethyl)benzene (0.0108 mL, 0.0791 mmol), and potassium carbonate (0.0237 g, 0.171 mmol) in dimethylformamide (0.96 mL) and stir for 15 min. Then purify the reaction mixture by ion exchange chromatography (SCX resin, methanol→2 M ammonia in methanol) to provide 0.0204 g (64%) of the title compound as an off-white foam: high resolution mass spectrum (electrospray): m/z calc for C25H28N3O2 402.2182, found 402.2182; 1H NMR (methanol-d4): 8.66 (d, 1H, J=2.0 Hz), 8.28 (dd, 1H, J=2.9, 8.3 Hz), 7.37 (d, 2H, J=7.8 Hz), 7.33-7.27 (m, 2H), 7.27-7.18 (m, 3H), 7.12 (d, 2H, J=8.3 Hz), 7.01 (d, 1H, J=8.8 Hz), 3.15 (d, 2H, J=11.2 Hz), 2.97-2.85 (m, 3H), 2.73-2.65 (m, 2H), 2.19 (q, 2H, J=11.2 Hz), 2.03-1.74 (m, 3H), 1.59 (dq, 1H, J=4.4, 12.7 Hz).
