A general synthesis of 6-trichloromethylpterin, 2-chloro-3-trichloromethylquinoxaline and 2-amino-7-trichloromethyl-1,8-naphthyridine along with a series of trichloromethyl heterocycles (1–11) has been reported in one-pot mild neutral condition in good yield. This method is compared with the usual method using phosphorus pentachloride in phosphorus oxychloride.
