실험 절차

A solution of sodium nitrite (0.34 g, 5 mmol) in water (10 ml) was added slowly to a cold (0°-5° C. suspension of (2,3-dihydro-6-sulfamoyl-2,4,4-trioxo-1H-thieno[2,3-b][1,4]thiazin-3-yl)acetic acid hydrazide (1.75 g, 5 mmol) in 1N HCl (150 ml). The reaction mixture was stirred for 0.5 hours in the cold and the resulting solid was collected, rinsed with water and air-dried to yield 1.05 g (2,3-dihydro-2,4,4-trioxo-6-sulfamoyl-1H-thieno-[2,3-b][1,4]thiazin-3-yl)acetyl azide.
