Procedure

Following general procedure II, 6-chloro-N-{trans-4-[(dimethylamino)methyl]-cyclohexyl}-3-(methylsulfonyl)-1,5-naphthyridin-4-amine (61 mg, 0.15 mmol) was reacted with 2-chloro-6-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (63 mg, 0.23 mmol) followed by formation of the dihydrochloride salt to afford the desired product (52 mg, 59%) as a light yellow solid: 1H NMR (500 MHz, CD3OD) δ 8.90 (s, 1H), 8.50 (d, J=8.9 Hz, 1H), 8.35 (d, J=9.0 Hz, 1H), 8.04 (t, J=1.8 Hz, 1H), 7.90 (dd, J=11.5, 2.2 Hz, 1H), 5.77-5.67 (m, 1H), 3.38 (s, 3H), 3.09 (d, J=6.6 Hz, 2H), 2.94 (s, 6H), 2.51-2.44 (m, 2H), 2.08-1.97 (m, 3H), 1.76-1.64 (m, 2H), 1.46-1.34 (m, 2H). ESI MS m/z 507 [M+H]+; HPLC 99.0% (AUC), tR=9.81 min.
