Participants

Reaction Steps

The 4-(4-hydroxybenzothiazol-2-yl)benzoic acid (6.9 g) obtained in Example 3 was dissolved in 15 ml of pyridine, and 2.6 g of acetic anhydride was added dropwise. The mixture was stirred at room temperature for 2 hours, and 160 ml of cyclohexane was added. The precipitated crystals were collected by filtration, washed with cyclohexane and then diethyl ether, and recrystallized from acetonitrile to give 4.0 g of 4-(4-acetoxybenzothiazol-2-yl)benzoic acid.
