Procedure

Following general procedure II, 1-(6-chloro-4-{trans-4-[(dimethylamino)methyl]-cyclohexylamino}-1,5-naphthyridin-3-yl)ethanone (76 g, 0.21 mmol) was reacted with (4-hydroxyphenyl)boronic acid (43 g, 0.32 mmol) followed by formation of the dihydrochloride salt to afford the desired product (35 g, 34%) as a yellow solid: 1H NMR (500 MHz, CD3OD) δ 9.11 (s, 1H), 8.41 (d, J=8.9 Hz, 1H), 8.28 (d, J=8.9 Hz, 1H), 8.03-7.97 (m, 2H), 7.04-6.98 (m, 2H), 5.73-5.62 (m, 1H), 3.11 (d, J=6.8 Hz, 2H), 2.94 (s, 6H), 2.75 (s, 3H), 2.50-2.42 (m, 2H), 2.06-1.99 (m, 3H), 1.73-1.61 (m, 2H), 1.40-1.27 (m, 2H); ESI MS m/z 419 [M+H]+; HPLC>99% (AUC), tR=9.24 min.
