Butyryl chloride (0.31 mL, 2.94 mmol) was added to a solution of N-[4-(4-oxo-piperidin-1-yl)-phenyl]amine (which was obtained in Example 224) (0.70 g, 2.77 mmol) and triethylamine (1.9 mL, 13.9 mmol) in anhydrous methylene chloride(10 mL). The reaction was stirred overnight. The reaction was quenched with water (50 mL) and washed with methylene chloride (3×20 mL). The organic extracts were combined, dried (sodium sulfate) and concentrated. The desired product was isolated using silica gel flash chromatography to give the title compound as a yellow solid (0.41 g); 1H NMR (300 MHz, CDCl3) δ 1.01 (t, 3H, J=7.38 Hz), 1.72 (m, 2H), 2.29(t, 2H, J=7.62 Hz), 2.55(t, 4H, J=6.03 Hz), 3.55(t, 4H, J=5.97 Hz), 6.95(d, 2H, J=7.91), 7.42(d, 2H, J=8.97 Hz). MS (ES) m/z: 260.9(MH+); HRMS found for C15H20N2O2: 260.1511. Anal. Calcd. for C, 69.20; H, 7.74; N, 10.76. Found: C, 69.03; H, 7.94; N, 10.59.
