title: Synthesis and anti-inflammatory activity of 4H-1,4-benzothiazines.
abstract: A new series of 4H-1,4-benzothiazine derivatives have been synthesized. These products were obtained by treatment with SO2Cl2 in dry ether at room temperature of 1,3-benzothiazolines N-acetylated. The 1,3-benzothiazolines were prepared by condensation in benzene of 2-aminothiophenol with several ketones, in the presence of p-toluenesulphonic acid as catalyst. Preliminary pharmacological studies on the anti-inflammatory activity of these compounds are reported.
