実験手順

20 g of 2-(p-methoxyphenyl)-6-methoxybenzothiazole are refluxed in a mixture of 100 ml of glacial acetic acid and 200 ml of concentrated aqueous HBr with stirring. After 14 hours the mixture is cooled down to room temperature and filtered with suction, and the filter residue is washed with water and recrystallized from ethanol. The yield is 17.2 g (95% of theory); melting point: 284°-286° C.

後処理
