Reaction Steps
To a solution of methyl 1H-imidazole-4-carboxylate (417 mg, 3.3 mmol) in DMF (10 mL) was added sodium hydride (130 mg, 3.3 mmol). After being stir for 1 h at room temperature, 2-chloro-4-(trifluoromethyl)pyridine (500 mg, 2.8 mmol) was added. The mixture was stirred at 80° C. overnight. After being cooled to room temperature, ethyl acetate was added. The solution was washed with brine several times, dried (MgSO4) and concentrated. Chromatography on silica gel eluting with EtOAc/hexanes (1:1) afforded the title compound (120 mg). MS (M+H) 272.1.
