Procedure
Into a solution of methyl 3-{[(4-{3-[1-(tert-butoxycarbonyl)-4-piperidinyl]anilino}-4-oxobutyl)amino]carbonyl}-4-(4-fluorophenyl)-6-methyl-2-oxo-1,2,3,4-tetrahydro-5-pyrimidinecarboxylate (40.9 mg, 0.0628 mmol) in dichloromethane (2.00 mL) at 0° C. was slowly added trifluoroacetic acid (71.6 mg, 0.628 mmol). The reaction mixture was stirred at room temperature for 10 min and concentrated in vacuo. The residue was dissolved in iso-PrOH/CHCl3 (1:3, 10 mL) and basified to pH 11 with 10% KOH solution, washed with H2O, followed by brine. The organic layer was dried over MgSO4 and concentrated in vacuo to afford the desired product (34.6 mg, 99%): 1H NMR (400 MHz, CDCl3) δ 8.00 (m, 3H), 7.67 (s, 1H), 7.35-7.27 (m, 4H), 7.04-6.98 (m, 3H), 6.65 (s, 1H), 3.72 (s, 3H), 3.5-3.48 (m, 2H), 3.20-3.11 (m, 3H), 2.42 (t, 2H, J=7.5 Hz), 2.36 (s, 3H), 2.13-2.06 (m, 2H), 1.97-1.88 (m, 4H); ESMS m/e: 552.3 (M+H)+.
