Provided is a simple and efficient production process of a nucleobase having a perfluoroalkyl group.
A nucleobase (for example, uracils, cytosines, adenines, guanines, hypoxanthines, xanthines, or the like) is reacted with a perfluoroalkyl halide in the presence of a sulfoxide, a peroxide and an iron compound to produce a perfluoroalkyl-substituted nucleobase, which is useful as an intermediate for medical drugs, economically.

Nucleobases are perfluoroalkylated in a one step process with a perfluoroalkyl halide in the presence of a sulfoxide, a peroxide and an iron compound. Compounds so produced are useful as medicinal drugs, intermediates for medicinal drugs and agricultural chemicals.
A compound of the formula:
wherein B is a purin-9-yl group or a heterocyclic isostere of a purin-9-yl group; or a pyrimidin-1-yl group or a heterocyclic isostere of a pyrimidin-1-yl group; A is -CH- or A-G taken together is -C(=O)-, -C(=CH₂)-, -C(OH)(CH₂OH)- or
and G and D are functional groups; or a pharmaceutically acceptable salt or ester thereof.
式中的化合物:
其中 B 是嘌呤-9-基团或嘌呤-9-基团的杂环异构体;或嘧啶-1-基团或嘧啶-1-基团的杂环异构体;A 是-CH-或 A-G 合起来是-C(=O)-、-C(=CH₂)-、-C(OH)(CH₂OH)-或
且 G 和 D 为官能团;或其药学上可接受的盐或酯。
