Procedure

Following general procedure II, 1-{6-chloro-4-[trans-4-(dimethylamino)cyclohexyl amino}-1,5-naphthyridin-3-yl)ethanone (45 mg, 0.12 mmol) was reacted with 2-chloro-6-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (47 mg, 0.17 mmol) followed by formation of the dihydrochloride salt to afford the desired product (6.9 mg, 11%) as an off-white solid: 1H NMR (500 MHz, CD3OD) δ 9.17 (s, 1H), 8.47 (d, J=9.0 Hz, 1H), 8.34 (d, J=9.0 Hz, 1H), 8.00 (s, 1H), 7.91 (dd, J=11.4, 2.2 Hz, 1H), 5.69-5.59 (m, 1H), 3.52-3.45 (m, 1H), 2.92 (s, 6H), 2.76 (s, 3H), 2.63-2.56 (m, 2H), 2.33-2.26 (m, 2H), 1.89-1.71 (m, 4H). ESI MS m/z 457 [M+H]+; HPLC>99% (AUC), tR=9.32 min.
