Procedure
A solution of 2-(5-tert-butyl-2-methyl-2H-pyrazol-3-yl)-4-chloro-6-(2-trifluoromethyl-phenyl)-3H-imidazo[4,5-c]pyridine (101 mg, 0.232 mmol, Compound #74 freebase prepared according to Example 16, STEPS A, B and C) in DCM (2 mL) was treated with SO2Cl2 (28.3 μL, 0.348 mmol) and the resulting mixture was stirred at room temperature for 14 h. The resulting mixture was then diluted with MeOH (3 mL) and the solvent was removed under reduced pressure. The residue was chromatographed on a 25-g SiO2 pre-packed column eluting with 0:1-3:7 EtOAc/hexanes to yield 2-(5-tert-butyl-4-chloro-2-methyl-2H-pyrazol-3-yl)-4-chloro-6-(2-trifluoromethyl-phenyl)-3H-imidazo[4,5-c]pyridine. 1H-NMR (400 MHz, CD3OD) δ: 7.84 (d, J=7.8 Hz, 1H), 7.69-7.76 (m, 1H), 7.68 (s, 1H), 7.62-7.67 (m, 1H), 7.59 (d, J=7.6 Hz, 1H), 4.14 (s, 3H), 1.45 (s, 9H). Mass Spectrum (LCMS, ESI pos.): Calculated for C21H18Cl2F3N5: 468.1 (M+H); Measured: 468.1.
