A novel and facile copper-catalyzed methylation of sulfonamides was herein demonstrated. The practical transformation took place readily under the oxidative conditions, and N-methyl amides (23 examples) were successfully furnished in high efficiency (up to 90% yields). Dicumyl peroxide was considered to act not only as the oxidant in the system, but also methyl donor for the methylation protocol.

The invention discloses a method for synthesizing TNNI3K inhibitors, proceeding from interval tetrabromobensoate sulfonamides, containing double-imidazole ligand iridium complex and under the action of the weak catalytic activation methanol instead of high toxicity halogenated methane get methylation product, further with the ammonia generating uhlmann coupling reaction, the final with 4 - chloro-pyrrolo pyrimidine nucleophilic substitution reaction to obtain TNNI3K inhibitors. The present invention through the use of iridium metal complex as the methylation reaction catalyst, the reaction conditions are more moderate and high yield, without the need of high temperature and high pressure, nitrogen protection, severe conditions such as the reaction for a long time, the last step nucleophilic substitution reaction we adopt a microwave reactor greatly shorten the reaction time.
