Reaction Steps

To a solution of tert-butyl 4-((trans-4-((3-acetyl-6-(3,5-dichloro-4-hydroxyphenyl)quinolin-4-yl)amino)cyclohexyl)methyl)piperazine-1-carboxylate (50 mg, 0.80 mmol) in THF (5 mL) was added aqueous 1 N HCl (4 mL) and the reaction mixture was heated at 65° C. for 4 h. The reaction mixture was cooled to room temperature and concentrated. The resultant residue was purified by preparative HPLC (C18 silica, 10-90% acetonitrile/water with 0.05% TFA). The residue was dissolved in methanol (5 mL) and HCl (1 M in water, 2.0 mL, 2 mmol) was added. The resultant solution was concentrated to give the desired product (19.9 mg, 41%) as an off-white solid. 1H NMR (500 MHz, MeOD) δ 9.10 (s, 1H), 8.48 (s, 1H), 8.28 (dd, J=8.7, 1.8 Hz, 1H), 7.97 (d, J=8.7 Hz, 1H), 7.73 (s, 2H), 4.57-4.53 (m, 1H), 3.67-3.63 (br s, 4H), 3.63-3.31 (br s, 2H), 3.14-3.10 (br s, 2H), 2.74 (s, 3H), 2.46 (d, J=12.2 Hz, 2H), 2.18 (d, J=12.8 Hz, 2H), 2.08 (br s, 1H), 1.80 (q, J=12.4 Hz, 2H), 1.41-1.34 (m, 2H). ESI MS m/z 527 [C28H32Cl2N4O2+H]+; HPLC>99% (AUC), tR=9.49 min.
