Participants

Reaction Steps

The 4-hydroxy-2-(4-methoxyphenyl)benzothiazole (4.0 g) obtained in Example 2 was added to 40 ml of acetic anhydride, and the mixture was refluxed for 1 hour. After the reaction, the reaction mixture was dried under reduced pressure. The residue was washed with a small amount of cyclohexane, and recrystallized from cyclohexane and ethyl acetate to give 4.0 g of 4-acetoxy-2-(4-methoxyphenyl)benzothiazole.
