Procedure

tert-Butyl 6-[[[6-(8-methyl-4-oxo-4H-1,3-benzothiazin-2-yl)-2-pyridyl]carbonyl]amino]hexylcarbamate (0.30 g, 0.60 mmol) was dissolved in dioxane (10 ml), and 4 N hydrochloric acid in dioxane (1.0 ml. 4.00 mol) was added thereto. The reaction mixture was stirred at room temperature for 24 hrs. The precipitates were collected by filtration and recrystallized from diisopropyl ether-methanol to give the titled compound (0.05 g, 20%) as pale yellow crystals.
