Procedure

[4-(5-Hydroxy-5,6,7,8-tetrahydro-[1,8]naphthyridin-3-yl)phenyl]-(4-methylpiperazin-1-yl)methanone (20 mg) was reacted with 3-chlorophenol (21.8 mg) as in General Procedure 12. Silica gel chromatography using a gradient of 0-15% methanol/CH2Cl2 as the eluting solvent gave the title compound as a yellow foam (50% yield). LCMS: m/z=463.12 (M+H+), 1H-NMR (CDCl3, 400 MHz) δ 2.00-2.12 (m, 1H), 2.27-2.33 (m, 1H), 2.33 (s, 3H), 2.34-2.6 (m, 4H), 3.4-3.7 (m, 4H), 3.7-3.9 (m, 2H), 5.18 (bs, 1H), 5.38 (t, J=3.6 Hz, 1H), 6.91 (dd, J=1.6 and 8.3 Hz, 1H), 6.99-7.04 (m, 2H), 7.23-7.27 (m, 1H), 7.43-7.50 (m, 4H), 7.61 (d, J=2.0 Hz), 8.30 (d, J=2.2 Hz).
