Participants

Reaction Steps

To a solution of tert-butyl [2-({4-[2-anilino-1-(anilinocarbonyl)-1-methyl-2-oxoethyl]benzoyl}amino)phenyl]-carbamate (14 mg, 0.024 mmol) in CH2Cl2 (3 mL) at room temperature was added trifluoroacetic acid (1 mL). The reaction mixture was stirred at room temperature 30 min and concentrated. Purification by reverse phase HPLC (10% to 95% MeCN in water) gave 2-(4-{[(2-aminophenyl)amino]carbonyl}-phenyl)-2-methyl-N,N′-diphenylmalonamide (12 mg, TFA salt, 84%) as a white solid: 1H NMR (600 MHz, CDCl3) δ 9.77 (s br, 1H), 9.18 (s br, 2H), 7.87 (d, J=6.2 Hz, 21-1), 7.45-7.42 (m, 6H), 7.34-7.28 (m, 5H), 7.17-7.04 (m, 5H), 6.18 (s br, 21-1), 2.05 (s, 3H); ESIMS calcd 479.2 (M++H), found 479.2 (M++H).
