実験手順
To a solution of 2.0 g of tetrafluoroisophthalonitrile in 20 ml of acetonitrile, 0.6 ml of 28% aqueous ammonia was dropwise added. After the dropwise addition, the mixture was stirred at room temperature for one hour. An aqueous sodium bicarbonate solution was added to the mixture and the resultant mixture was extracted with chloroform and was washed with an aqueous sodium chloride solution. After drying with sodium sulfate, the chloroform was distilled off to obtain yellow crystal. The resultant crystal was recrystallized from chloroform to obtain 1.2 g (61% yield) of the desired compound No. 1.
