Reaction Conditions

Reaction Steps

To 2-(mesityloxy)-N-[4-(2-benzyloxyphenyl)-1H-imidazol-2-yl]acetamide (Compound 1) (530 mg; 1.2 mmol) obtained in Example 1, 25% hydrobromic acid/acetic acid solution (8.0 mL) was added, and the mixture was stirred for 1 hour at 60° C. To the reaction solution, chloroform (100 mL) was added, and the mixture was washed with saturated aqueous sodium bicarbonate solution. The organic layer was dried over anhydrous magnesium sulfate, and then distilled under reduced pressure. The resulting crystals were dispersed in diethyl ether, collected by filtration and dried to give 180 mg of the title compound (yield 43%) expressed by the following formula (Ex. 2).
