Procedure

In a solution of 0.16 g of N-[2,2,2-trifluoro-1-(4-formylphenyl)ethyl]isobutyramide in 4.0 mL of methanol and 1.0 mL of water, 0.075 g of hydroxylamine hydrochloride was added, and stirred at room temperature for 1.5 hour. After the completion of the reaction, the reaction mixture was diluted with 20 mL of ethyl acetate, washed with water (10 mL×1), and the organic phase was dehydrated with and dried over saturated sodium chloride aqueous solution and anhydrous magnesium sulfate in that order, and the solvent was distilled off under reduced pressure to obtain 0.20 g of the aimed product as white crystal.
