実験手順
2-(6-Methylthio-2-pyridyl)-4H-1,3-benzothiazine-4-one (0.28 g, 1.0 mmol) obtained in Example 43 was dissolved in chloroform (30 ml). To the stirred mixture was added dropwise a solution of 3-chloroperbenzoic acid (ca. 70%, 0.25 g, 1.0 mmol) in chloroform (10 ml). The reaction mixture was stirred for 1 hr and concentrated under reduced pressure. The residue was subjected to a silica gel column chromatography and eluted with 10% methanol-chloroform and recrystallized from ethanol to give the titled compound (0.19 g, 64%) as crystals.
