Procedure
Following general procedure II, 1-(6-chloro-4-{3-[2-(pyrrolidin-1-yl)ethyl]phenylamino}-1,5-naphthyridin-3-yl)ethanone (59 mg, 0.15 mmol) was reacted with 2,6-dichloro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (65 mg, 0.23 mmol) followed by formation of the dihydrochloride salt to afford the desired product (67 mg, 75%) as a yellow solid: 1H NMR (500 MHz, D2O) δ 9.13 (s, 1H), 8.13 (d, J=9.0 Hz, 1H), 8.01 (d, J=9.1 Hz, 1H), 7.64 (t, J=7.8 Hz, 1H), 7.41 (d, J=7.4 Hz, 1H), 7.32 (d, J=7.9 Hz, 1H), 6.79 (s, 1H), 6.66 (br s, 2H), 3.36-3.27 (m, 2H), 2.78 (s, 3H), 2.74-2.64 (m, 2H), 2.62-2.42 (m, 4H), 1.87-1.72 (m, 4H); ESI MS m/z 521 [M+H]+; HPLC 98.9% (AUC), tR=10.34 min.
