실험 절차

A solution of 5-tert-butyl-4-chloro-2-methyl-2H-pyrazole-3-carboxylic acid [2-methoxy-3-nitro-6-(2-trifluoromethyl-phenyl)-pyridin-4-yl]-amide (149 mg, 0.291 mmol, prepared as described in STEP A above) in AcOH (10 mL) was treated with iron powder (81.3 mg, 1.46 mmol), and the resulting mixture was heated to 100° C. for 1.5 h. The cooled mixture was concentrated in vacuo, taken up in saturated aqueous NaHCO3 (50 mL), and extracted twice with EtOAc (40 mL). The combined organic extracts were dried over MgSO4 and concentrated in vacuo. The residue was purified on a 12-g SEPRA Si 50 SPE column (Flow rate=15 mL/min; Eluent=EtOAc-hexanes, 1:99 for 10 min, then 1:99 to 1:4 over 40 min) to yield 2-(5-tert-butyl-4-chloro-2-methyl-2H-pyrazol-3-yl)-4-methoxy-6-(2-trifluoromethyl-phenyl)-3H-imidazo[4,5-c]pyridine as a white solid. Mass Spectrum (LCMS, ESI pos.): Calculated for C22H21N5OClF3: 464.1 (M+H); Measured: 464.2.
