Procedure

Following general procedure D, (6-bromo-4-(4-(2-(dimethylamino)ethyl)phenylamino)quinolin-3-yl)(cyclopropyl)methanone (7.3 g, 16.7 mmol) was reacted with 2,6-dichloro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (5.6 g, 20 mol) to obtain the desired product which was dissolved methanol and treated with excess 1 N aq. HCl. During removal of the methanol via rotary evaporation a precipitate appeared which was filtered to obtain the desired product (5.6 g, 64% over 2 steps) as a yellow solid: 1H NMR (300 MHz, MeOD) δ 9.46 (s, 1H), 8.21 (dd, J=8.8, 1.9 Hz, 1H), 8.01 (d, J=8.8 Hz, 1H), 7.89 (s, 1H), 7.57 (d, J=9 Hz, 2H), 7.46 (d, J=9 Hz, 2H), 7.23 (s, 2H), 3.40 (m, 2H), 3.22 (m, 2H), 2.98 (s, 7H), 2.90 (t, J=4.8 Hz, 1H), 1.22 (m, 4H); ESI MS m/z 520 [C29H27Cl2N3O2+H]+; HPLC 99.1% (AUC), tR=10.54 min.
