Paragraph 0046-0047, (2020/05/08)
The invention discloses a preparation method of 5-bromo-2-chloro-7H-pyrrolo[2, 3-b] pyridine. According to the method, 2,4-chloro-7H-pyrrolo[2, 3-d] pyrimidine is used as a starting raw material, in the presence of zinc powder and acetic acid, selective d

This paper describes a mild phenyliodine diacetate mediated method for selective chlorination, bromination, and iodination of indole C-H bonds using sodium halide as a source for analogous halogenations. The combination of NaX and phenyliodine diacetate provides an invincible system for halogenation of indoles. This protocol was compatible with a wide array of indole substrates and provides straight forward access to potential halogenated arenes.

An efficient four step synthesis from commercial indoles of isogranulatimide analogues is reported. In the new compounds, the imidazole moiety is replaced by a pyrrole unit, the indole part is substituted or not in 5-position and the nitrogen of the imide moiety bears or not a methyl substituent.
