実験手順

4-(4-Benzo[1,3]dioxol-5-yl-5-pyridin-2-yl-1H-imidazol-2-yl)benzoic acid (prepared according to the method of Example 1) (379 mg; 0.98 mmol ) was suspended in dry dichloromethane (20 ml) and treated with oxalyl chloride (2 ml) and N,N-dimethylformamide (1 drop). This mixture was stirred at ambient temperature for 5 h then evaporated to dryness under reduced pressure to give the title compound as a yellow powder.
