Reaction Steps
Methyl 4-(2-pyridin-2-yl-1H-imidazol-4-yl)benzoate (from Step 1, 19.55 g, 70 mmol) was dissolve in THF (160 mL), to which was added Cs2CO3 (29.6 g, 91 mmol) at 0° C. After stirring for 5 min, MeI (11 mL, 175 mmol) was added. After stirring overnight at rt, the reaction was quenched with aq NH4Cl. The product was extracted with EtOAc and the organic layer was washed with water, brine, dried over MgSO4, filtered, and concentrated. The residue was subject to silica column chromatography (0-20% EtOAc in hexanes) to give 12.5 g of methyl 4-(1-methyl-2-pyridin-2-yl-1H-imidazol-4-yl)benzoate. LCMS: m/z 294 (M+H)+.
