6-Bromo-4-(3-chlorophenoxy)-1,2,3,4-tetrahydro-[1,8]naphthyridine (20 mg) was reacted with 4-[3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)phenyl]morpholine (23.9 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 foam (49% yield). LCMS: m/z=422.18 (M+H+), 1H-NMR (CDCl3, 400 MHz) δ 2.00-2.11 (m, 1H), 2.22-2.26 (m, 1H), 3.19 (t, J=4.8 Hz, 4H), 3.40-3.45 (m, 1H), 3.58-3.64 (m, 1H), 3.88 (t, J=4.8 Hz, 4H), 5.14 (bs, 1H), 5.37 (t, J=1.0 Hz, 1H), 6.82-6.92 (m, 2H), 6.92 (s, 1H), 6.95-7.02 (m, 2H), 7.03-7.08 (m, 1H), 7.20-7.33 (m, 2H), 7.55 (d, J=1.9 Hz, 1H), 8.27 (d, J=2.1 Hz, 1H).
