| titleOfInvention | Process for producing benzothiazine derivative |
| abstract | The present invention relates to a novel process for the preparation of 4-hydroxy-2-methyl-N- (2-pyridyl) -2H-1,2-benzothiazine-3-carboxamide-1,1-dioxide in the form of a saccharide. sodium chloride is reacted with chloroacetic acid 2- (2-methoxyethoxy) ethyl ester, the resulting saccharin-2-acetic acid (2- (2-methoxyethoxy) ethyl) ester is subjected to ring expansion by heating with alkali metal alcoholate. 4-Hydroxy-2H-benzothiazine-3-carboxylic acid [2- (2-methoxyethoxy) ethyl] ester 1,1-dioxide was subjected to methylation and the resulting 4-hydroxy-2-methyl- 2H-benzothiazine-3-carboxylic acid [2- (2-methoxyethoxy) ethyl] ester-1,1-dioxide is reacted with 2-aminopyridine. -1- |
