Reaction Steps

2-(3-Hydroxypropyl)-5,6,7-trimethoxybenzothiazole (388 mg) was dissolved in dichloromethane (5 mL), carbon tetrabromide (590 mg) and triphenylphosphine (431 mg) were added to the solution at room temperature, and the mixture was vigorously stirred for 1 hour. Water was added to conduct extraction with dichloromethane, and the resultant organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate and then concentrated under reduced pressure. The residue was purified by column chromatography on silica gel (ethyl acetate:hexane=1:9) to obtain the title compound.
