실험 절차

N-{4-[4-[(4-chlorophenyl)(hydroxy)methyl]-5-(1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-imidazol-2-yl)-1,3-thiazol-2-yl]pyridin-2-yl}acetamide (0.120 g, 0.216 mmol) was dissolved in DCM (5 mL) and trifluoroacetic acid (5.0 mL, 65 mmol) was added. The mixture was stirred at room temperature overnight. The solvent was evaporated, azeotroped with toluene and purified using column chromatography on silica gel (0 to 10% MeOH in DCM) to give the title compound (0.050 g, 50%). LCMS: (FA) ES+, 426, 428. 1H NMR (400 MHz, d4-methanol) δ: 8.68 (s, 1H), 8.38 (d, J=5.24 Hz, 1H), 7.64 (dd, J=5.25, 1.60 Hz, 1H), 7.45-7.37 (m, 2H), 7.30-7.23 (m, 2H), 7.25-7.09 (m, 2H), 6.37 (s, 1H), 2.20 (s, 3H).
