Document Type and Number:

Japanese Patent JPS5899489

Kind Code:

A

Abstract:

NEW MATERIAL:4-Hydroxy-2-methyl-N-( 6-halogeno-2-pyridyl )-2H-[1]benzothieno-[2,3-e]-1,2-thazine-3-carboxamide, 1,1-dioxide of formulaI(X is halogen) and its salt.

EXAMPLE: 4-Hydroxy-2-methyl-N-( 6-chloro-2-pyridyl )-2H-[1]benzothieno-[2,3- e]-1,2-thiazine-3-carboxamide 1,1-dioxide.

USE: Antiphlogistic agent having durable effect and low toxicity and troubles in the digestive tracts.

PROCESS: The derivative of formulaIcan be prepared by the condensation reaction of the ester of formula II (R is 1W4C lower alkyl) with the aminopyridine compound of formula III (X is halogen) in an inert solvent such as xylene.
