実験手順

The title compound was prepared according to General Method 15 using 2-amino-5-tert-butyl-benzothiazole-6-thiol (7.0 g, 29 mmol), pyridine (2.3 g, 29 mmol), tosyl bromide (6.9 g, 29 mmol), carbon tetrachloride (100 mL), and EtOAc (100 mL). The crude reaction mixture was purified by flash chromatography (5% EtOAc in hexanes to 50% EtOAc in hexanes as eluents). MS(APCI): 393 (M+H).
