Reaction Steps

To a mixture of 6-(bis(4-chlorophenyl)methyl)-4-(piperidin-4-ylamino)quinolin-2(1H)-one (250 mg, 0.523 mmol0, N,N′-bis-tert-butoxycarbonylthiourea (158.8 mg, 0.575 mmol) and triethylamine (0.22 mL, 1.57 mmol) in 3 mL DMF was added mercuric chloride (170.2 mg, 0.63 mmol) at 0° C. The reaction was stirred for 3 h at 0° C. and then quenched with EtOAc. The reaction was filtered through CELITE. The filtrate was washed two times with water, then dried over anhydrous Na2SO4, filtered and concentrated. The resulting residue was purified on ISCO with MeOH—CH2Cl2 and re-purified on HPLC (40-90% CH3CN (0.1% TFA)/H2O (0.1% TFA)) to yield (Z)-tert-butyl ((4-((6-(bis(4-chlorophenyl)methyl)-2-oxo-1,2-dihydroquinolin-4-yl)amino)piperidin-1-yl)((tert-butoxycarbonyl)imino)methyl)carbamate.
