Abstract: | The reaction of 3-amino-6-chloro-2-mercaptopyridine with phenacyl halides has been studied, and a number of 3-aryl-7-chloro-2H-pyrido-2,3-b]-1,4-thiazines have been synthesized. Two types of intermediate compounds have been isolated: 2-amino-6-chloro-2-phenacyl-thiopyridines and 3-aryl-7-chloro-3-hydroxy-1,2-dihydropyrido2,3-b]-1,4-thiazines.For part VI, see 3]. |
