Procedure

Following general procedure II, 1-{6-chloro-4-[(1-methylpiperidin-4-yl)amino]-1,5-naphthyridin-3-yl}ethanone (70 mg, 0.22 mmol) was reacted with 2,6-dichloro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (95 mg, 0.33 mmol) to afford the desired product (52 mg, 53%) as a yellow solid: 1H NMR (500 MHz, CD3OD) δ 8.85 (s, 1H), 8.09-8.01 (m, 2H), 7.94 (s, 2H), 5.74-5.70 (m, 1H), 2.95-2.92 (m, 2H), 2.68 (s, 3H), 2.51 (t, J=11.7 Hz, 2H), 2.37 (s, 3H), 2.33-2.25 (m, 2H), 1.73-1.71 (m, 2H); ESI MS m/z 445 [M+H]+; HPLC>99% (AUC), tR=9.03 min.
