摘要

The requisite N-(2-alkynyl)anilines can be easily prepared by the reaction of propargylic mesylates or bromides with anilines. 17 We initially studied the reaction of N-(3-phenyl-2-propynyl)aniline (1) and I 2 . The reaction has been examined with or without various bases such as NaHCO 3 , NaOCO 2 CH 3 , triethylamine, and pyridine and in the presence of different solvents and varying amounts of I 2 . The optimal reaction conditions developed thus far include stirring of 0.30 ...
