摘要

Procedure for the obtaining of 4-hydroxy-2-methyl-N- (2-pyridyl) -2H-1,2-benzotiazine-3-carboxamide-1,1-dioxide. Consists of the reaction of 3,4-dihydro-4,4-ethylenendioxo-2metil-N- (2-piridyl) -2H-1,2-benzotiazine-3-carboxamide-1,1-dioxide with a strong acid, such as acid aqueous chlorihdrical, in a solvent as acetic acid at a temperature comprised between 0 and 100c. This composite has pharmacological applications for its analgesic and anti-inflammatory activities. (Machine-translation by Google Translate, not legally binding)
