6-Bromo-4-(3-chlorophenoxy)-1,2,3,4-tetrahydro-[1,8]naphthyridine (20 mg) was reacted with 4-morpholinophenylboronic acid (20.7 mg) as in General Procedure 13. Silica gel chromatography using a gradient of 0-100% ethyl acetate/hexane as the eluting solvent gave the title compound as a yellow solid (73% yield). M.p. 124-126° C., LCMS: m/z=422.28 (M+H+), 1H-NMR (CDCl3, 400 MHz) δ 2.0-2.11 (m, 1H), 2.22-2.5 (m, 1H), 3.17 (t, J=4.7 Hz, 4H), 3.38-3.48 (m, 1H), 3.54-3.67 (m, 1H), 3.87 (t, J=4.7 Hz, 4H), 5.10 (s, 1H), 5.37 (t, J=1.0 Hz, 1H), 6.88-7.02 (m, 4H), 7.03-7.07 (m, 1H), 7.21-7.26 (m, 1H), 7.37 (d, J=8.6 Hz, 2H), 7.56 (d, J=1.9 Hz, 1H), 8.25 (d, J=1.9 Hz, 1H).
