実験手順

2 N sulfuric acid (20 ml) was added to 2-(dimethoxymethyl)-4-(trifluoromethyl)-1H-imidazole obtained in Example (33a) (720 mg, 3.43 mmol), and the mixture was stirred at 90° C. for one hour. The reaction solution was neutralized with a 1 N aqueous sodium hydroxide solution, followed by extraction with ethyl acetate. Then, the organic layer was washed with brine, dried over anhydrous sodium sulfate and concentrated under reduced pressure, to obtain 0.376 g of the title compound as a white solid (67%).
