Procedure

tert-butyl 1-(5-(3-acetyl-6-(3,5-dichloro-4-hydroxyphenyl)quinolin-4-ylamino)pyridin-2-yl)piperidin-3-ylcarbamate (52 mg, 0.080 mmol) was dissolved in dichloromethane (5 mL). To this solution was added a 2.0 M HCl solution in diethyl ether (2 mL) the mixture was stirred for 16 h at room temperature where a precipitate formed. The precipitate was filtered off, washed with dichloromethane (10 mL), dried under vacuum to obtain the desired product as the HCl salt (40 mg, 79%) as a yellow-brown solid: 1H NMR (500 MHz, DMSO-d6) δ 10.56 (s, 1H), 8.94 (s, 1H), 8.28 (s, 1H), 8.05 (s, 1H), 7.87 (s, 1H), 7.29 (s, 2H), 4.17 (s, 1H), 3.95 (s, 3H), 2.66 (s, 3H), 2.38 (s, 4H), 2.23 (s, 2H), 2.03 (s, 2H), 1.67 (s, 1H), 1.51 (s, 2H), 1.30 (s, 3H); ESI MS m/z 454, [C25H28ClN3O3+H]+; HPLC 99.5% (AUC), tR=9.99 min.
