Paragraph 0017-0031, (2018/03/13)
The invention relates to a method for synthesizing 2-amino-3-iodo-5-chloropyridine. The method comprises the steps of enabling 2-amino-5-chloropyridine and N-iodo succinimide, which serve as raw materials and are in the mass ratio of 1: (1.5-4.5), to react at the temperature of 10-102 DEG C in a proper solvent, so as to produce 2-amino-3-iodo-5-chloropyridine, and purifying, thereby obtaining a pure product 2-amino-3-iodo-5-chloropyridine. According to the method, the raw materials are relatively easily obtained and are reasonable in price; meanwhile, during preparation reaction, no heavy metal and corrosive gas are used, the reaction is mild, no special requirements on reaction equipment are required, and ordinary corrosion-resistant equipment can be applied to production; in addition, reaction conditions of the method are moderate.

The synthesis of 7-azaindoles from 3-alkynyl-2-aminopyridines using acidic conditions, namely, a mixture of trifluoroacetic acid (TFA) and trifluoroacetic anhydride (TFAA), is described. This methodology resulted in the synthesis of fifteen 7-azaindoles, with most containing substituents at the 2- and 5-positions. The majority of these were tested for antimicrobial activity against a range of bacteria and yeasts. The 7-azaindoles displayed the best activity against the yeasts, particularly against Cryptococcus neoformans, where activities as low as 3.9 μg ml-1 were observed.
