Reaction Steps

To a solution of 1H-imidazole-2-carboxylic acid (0.975 g, 8.7 mmol) in DMF (30 mL) were added aniline (0.67 mL, 8.7 mmol), EDC.HCl (2.54 g, 13.05 mmol) and HOBt (1.76 g, 13.05 mmol). The reaction mixture was stirred at room temperature for 21 hours. Then, it was poured into water and extracted with ethyl acetate. The combined organic layer was dried over sodium sulphate, filtered and concentrated. The crude residue was purified by flash chromatography (2% to 3% methanol in dichloromethane) to yield 1.55 g (96% yield) of the title compound.
