Procedure

2 ml of a 30% aqueous hydrogen peroxide solution was added to a mixture of 100 mg of 3-amino-2-cyano-5-trifluoromethylpyridine, 2 ml of a 10% aqueous sodium hydroxide solution and 6 ml of methanol, under ice cooling, and the mixture was stirred at room temperature for 1 hour. Water was added to the reaction mixture, and the mixture was extracted with t-butyl methyl ether. The organic layer was washed with a 10% aqueous sodium thiosulfate solution and dried over anhydrous magnesium sulfate, and then concentrated under reduced pressure to obtain 100 mg of 3-amino-5-trifluoromethylpyridine-2-carboxylic acid amide.
