Reaction Steps

To a solution of 4-amino-5-(2-(3-(2-(benzyloxy)ethoxy)-5-methoxybenzamido)-2-methylpropoxy)-2-methylquinoline-3-carboxylic acid (Example 38a, 237 mg, 0.5 mmol) in EtOH/EtOAc (1:1, 20 mL) was added 10% Pd/C (wet, 50 mg). The suspension was then stirred under an atmosphere of hydrogen at room temperature overnight. The Pd/C was filtered off, and the filtrate was concentrated. The residue was purified by HPLC (eluent: 10-100% MeOH in H2O) to give the title compound as an off-white solid (152 mg, 63%). 1H NR (400 MHz, DMSO-d6) δ 1.49 (s, 6H), 2.75 (s, 3H), 3.68 (t, J=5.2 Hz, 2H), 3.73 (s, 3H), 3.99 (t, J=5.2 Hz, 1H), 4.47 (s, 2H), 6.57 (s, 1H), 6.88 (s, 1H), 6.96 (s, 1H), 7.06 (d, J=7.6 Hz, 1H), 7.28 (d, J=8 Hz, 1H), 7.67 (t, J=8 Hz, 1H), 8.14 (s, 1H). MS 484 (MH+).
