Procedure

The title compound was prepared as described in Example BB-15 using toluene-4-thiosulfonic acid S-(2-amino-5-tert-butyl-benzothiazol-6-yl)ester (prepared in Example BB-1; 1.75 g, 4.47 mmol), acetyl chloride (4 mL), pyridine (5 mL), DMAP (0.3 g) and CH2Cl2 (20 mL). The crude product was purified by flash silica gel chromatography (20%-70% EtOAc in hexanes as eluents). MS(APCI): 435 (M+H).
