Procedure

A solution of N-(3-(2-cyclopropyl-5-(2-(methylamino)pyrimidin-4-yl)-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-imidazol-4-yl)-2-fluorophenyl)methanesulfonamide (78 mg, 0.14 mmol) in EtOH (2 mL) was treated with aqueous 6.0 N HCl solution and the resulting reaction was heated at 60° C. for 1 hour. LCMS indicated complete reaction, and the reaction was allowed to cool to room temperature. The volatiles were removed in vacuo, and the resulting residue was dissolved in DMSO and purified by reverse phase HPLC. Product fractions were combined, neutralized with saturated aqueous NaHCO3 solution (pH=6), and extracted with DCM (2×). The combined organic portions were dried (Na2SO4), and concentrated. The resulting free base (3A-1) was dissolved in ACN, treated with aqueous 1.0 N HCl solution, frozen, and lypholized to provide N-(3-(2-cyclopropyl-5-(2-(methylamino)pyrimidin-4-yl)-1H-imidazol-4-yl)-2-fluorophenyl)methanesulfonamide (23 mg) as the HCl salt (3A-2): LCMS(m/z) 402.9, (MH+), tR=0.44 minute; 1H NMR (300 MHz, CD3CO2D) δ 1.26-1.38 (m, 2H) 1.37-1.52 (m, 2H) 2.41-2.60 (m, 1H) 2.84 (br s, 3H) 3.12 (s, 3H) 7.03 (d, J=6.5 Hz, 1H) 7.29-7.41 (m, 1H) 7.44-7.59 (m, 1H) 7.69-7.84 (m, 1H) 8.29 (d, J=6.5 Hz, 1H).
