Procedure
N-[(4-cyano-3-fluoro-phenyl)-(3-methyl-3H-imidazol-4-yl)-methylene]-2-methylpropanesulfinamide (as described above in Step B) (1.50 g, 4.51 mmol) was dissolved in anhydrous THF (30 mL) at 0° C. to which a 3.0M solution of MeMgBr (4.50 mL, 13.5 mmol) in Et2O was added. The reaction was quenched with aq. NH4Cl solution, diluted with saturated NaHCO3 solution and extracted with CH2Cl2 (3×). The combined organic layers were dried (MgSO4), filtered, concentrated, and recrystallized from 95% EtOAc/Hexane to give the title compound.
