Reaction Steps

(4-(6-(3-aminopyrrolidin-1-yl)pyridin-3-ylamino)-6-(3-chloro-5-fluoro-4-hydroxyphenyl)quinolin-3-yl)(cyclopropyl)methanone (15 mg, 0.03 mmol) was suspended in methanol (1 mL) at 0° C. followed by dropwise addition of HCl in diethyl ether (2 M) until complete dissolution of the solid was observed. The solvent was removed under reduced pressure to afford the desired product (23 mg, quant.) as a yellow-brown solid. 1H NMR (500 MHz, MeOD) δ 9.39 (s, 1H), 8.28-8.19 (m, 2H), 8.16 (br s, 1H), 8.02 (d, J=8.8 Hz, 1H), 7.79 (dd, J=9.1, 2.7 Hz, 1H), 7.26-7.16 (m, 2H), 6.94 (d, J=9.2 Hz, 1H), 4.16-4.08 (m, 1H), 4.05-3.97 (m, 1H), 3.88-3.79 (m, 1H), 3.78-3.69 (m, 2H), 2.85 (br s, 1H), 2.64-2.53 (m, 1H), 2.34-2.21 (m, 1H), 1.25-1.15 (m, 4H).
