Abstract
PURPOSE: To prepare high-purity adenine in high yield, without isolating the intermediate, by reacting a malononitrile derivative with formic acid (derivative) in the presence of ammonia under heating, and catalytically reducing the product in the absence of ammonia.
CONSTITUTION: A malononitrile derivative of formula (Ar is aryl) (e.g. phenylazomalononitrile) is reacted with formic acid or formic acid or formic acid derivative (e.g. formamide) in the presence of 1.5W10 times mole of ammonia based on the arylazomalononitrile under heating, and the product is reacted under catalytic reduction conditions to obtain adenine. The catalytic reduction is carried out preventing the existence of ammonia, i.e. keeping the amount of ammonia in the reaction system to 0W5wt% based on the liquid component of the system. To prevent the existence of ammonia, it is preferable to use the release of ammonia under hot conditions and the bubbling of gas such as nitrogen gas in combination.
