Procedure

Following general procedure II, 1-(6-chloro-4-{trans-4-[(dimethylamino)methyl]cyclohexyl amino}-1,5-naphthyridin-3-yl)ethanone (20 mg, 0.055 mmol) was reacted with 2-chloro-6-methoxy-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (28 mg, 1.0 mmol) followed by formation of the dihydrochloride salt to afford the desired product (18 mg, 59%) as a yellow solid: 1H NMR (500 MHz, CD3OD) δ 9.13 (s, 1H), 8.49 (d, J=8.9 Hz, 1H), 8.32 (d, J=9.1 Hz, 1H), 7.81 (d, J=2.1 Hz, 1H), 7.58 (d, J=2.1 Hz, 1H), 5.80-5.70 (m, 1H), 4.03 (s, 3H), 3.08 (d, J=6.6 Hz, 2H), 2.93 (s, 6H), 2.76 (s, 3H), 2.49-2.39 (m, 2H), 2.08-1.96 (m, 3H), 1.72-1.62 (m, 2H), 1.47-1.35 (m, 2H). ESI MS m/z 483 [M+H]+; HPLC>99% (AUC), tR=9.62 min.
