Procedure

A solution of 2-(5-tert-butyl-4-chloro-2-methyl-2H-pyrazol-3-yl)-6-(2-chloro-phenyl)-4-methoxy-3H-imidazo[4,5-c]pyridine (159 mg, 0.370 mmol, prepared as described in Example 25) in DCM (10 mL) and treated with methanesulfonic acid (35.6 mg, 0.370 mmol) at room temperature for 1 h. The solution was concentrated in vacuo and the resulting solid was triturated with hexanes, filtered, washed with hexanes, air-dried, and placed under high vacuum for 30 min to yield 2-(5-tert-butyl-4-chloro-2-methyl-2H-pyrazol-3-yl)-6-(2-chloro-phenyl)-4-methoxy-3H-imidazo[4,5-c]pyridine methanesulfonic acid salt as a white solid. 1H-NMR (400 MHz, CD3OD) δ: 7.64-7.69 (m, 2H), 7.62-7.64 (m, 1H), 7.50-7.61 (m, 2H), 4.75-4.81 (m, 3H), 4.16 (s, 3H), 2.70 (s, 3H), 1.46 (s, 9H). Mass Spectrum (LCMS, APCI pos.) Calculated for C21H21N5OCl2: 430.1 (M+H), Measured: 430.2.
