実験手順

To 11.0 g of 5-methyl-2-(4-trifluoromethoxy-phenyl)-1H-imidazole-4-carboxylic acid ethyl ester in 40 ml of ethanol was added 40 ml of a 2N—NaOH solution and the reaction mixture was stirred at 100° C. for 17 hours. After such time the reaction mixture was cooled to +5° C. and treated with 80 ml of a 1N HCl solution. The precipitate was filtered, washed with water and dried under high vacuo to yield 8.3 g of a white powder.
