Procedure

To a solution of N-{4-(2-amino-4-thiazolyl)phenyl}-2-{(phenylmethyl)amino}acetamide (352 mg, 1.04 mmol, described in example 2), cyclohexanecarboxylic acid (140 mg, 1.09 mmol) and DIPEA (269 mg, 2.08 mmol) in DMF (5.2 mL) was added TBTU (350 mg, 1.09 mmol). The mixture was stirred at room temperature for 6 h. The reaction mixture was diluted with EtOAc (125 mL). The resulting solution was washed with saturated aqueous NaHCO3 (40 mL), H2O (40 mL), and brine (40 mL), then dried (MgSO4) and concentrated under reduced pressure. The residue was purified by flash chromatography (SiO2, CHCl3 : EtOH, 15:1) to yield the title compound (341 mg, 73% yield) as a white solid: M.p. 214.5-215.5°; 1H NMR (400 MHz, DMSO-d6) δ (2 rotamers, 1:1) 10.06, 9.92 (2 s, 1H), 7.73, 7.71 (2 d, J=8.5 Hz, 2H), 7.56, 7.55 (2 d, J =8.5 Hz, 2H), 7.20-7.41 (m, 5H), 7.01, 7.00 (2 s, 2H), 6.89, 6.88 (2 s, 1H), 4.70, 4.51 (2 s, 2H), 4.13, 4.02 (2 s, 2H), 2.64, 2.56 (2 broad t, J=10.5 Hz, 1H), 1.61-1.70 (m, 5H), 1.12-1.46 (m, 5H); MS (FAB) m/z 449 (MH)+ ; Anal. Calcd for C25H28N4O2S: C, 66.94; H, 6.29; N, 12.49. Found: C, 66.54; H, 6.29; N, 12.32.
