Reaction Steps

Following general procedure II, 1-{6-chloro-4-[(1-methylpiperidin-4-yl)methylamino]-1,5-naphthyridin-3-yl}ethanone (60 mg, 0.18 mmol) was reacted with 2,6-dichloro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (78 mg, 0.27 mmol) followed by formation of the dihydrochloride salt to afford the desired product (7.3 mg, 7.6%) as an off-white solid: 1H NMR (500 MHz, CD3OD) δ 9.18 (s, 1H), 8.48 (d, J=9.0 Hz, 1H), 8.35 (d, J=8.9 Hz, 1H), 8.11 (s, 2H), 4.60 (d, J=7.1 Hz, 2H), 3.65-3.59 (m, 2H), 3.09 (td, J=13.0, 2.8 Hz, 2H), 2.88 (s, 3H), 2.77 (s, 3H), 2.34 (br s, 1H), 2.27 (d, J=14.7 Hz, 2H), 1.80-1.67 (m, 2H); ESI MS m/z 459 [M+H]+; HPLC>99% (AUC), tR=9.39 min.
