Reaction Steps

To a suspension of tert-butyl (trans-4-((3-butyryl-6-(3-chloro-5-fluoro-4-hydroxyphenyl)quinolin-4-yl)amino)cyclohexyl)carbamate (36 mg, 0.065 mmol) in THF (3 mL) was added water (2 mL) and 6N aqueous HCl (2 mL). The resultant solution was heated at 65° C. for 4 h. The reaction mixture was cooled and concentrated. The resultant residue was triturated with diethyl ether. The residue was eluted through an ion-exchange column (using methanol and 7 N methanol in ammonia) to obtain the desired product (21.1 mg, 71%) as a yellow solid. 1H NMR (500 MHz, MeOD+TFA-d) δ 9.15 (s, 1H), 8.47 (s, 1H), 8.28 (dd, J=8.7, 1.8 Hz, 1H), 7.99 (d, J=8.7 Hz, 1H), 7.59 (s, 1H), 7.51 (d, J=11.4 Hz, 1H), 4.55 (br s, 1H), 3.13 (t, J=7.2 Hz, 2H), 2.53-2.49 (m, 2H), 2.26 (d, J=12.1 Hz, 2H), 1.94-1.74 (m, 4H), 1.68-1.62 (m, 2H), 1.06 (t, J=7.4 Hz, 3H). ESI MS m/z 456 [C25H27ClFN3O2+H]+; HPLC>99% (AUC), tR=10.83 min.
