Reaction Steps

To 0.76 g (11.5 mM) of 85%-potassium hydroxide, 50 ml of ethanol was added, followed by stirring at 65° C. and dissolving. To the resultant solution, 1.80 g (4.72 mM) of 2-(p-methoxycarbonylphenyl)-6-octylbenzothiazole was added, followed by stirring for 20 minutes at 65° C. After the reaction, the reaction mixture was poured into water and 1.5 ml of concentrated hydrochloric acid was added thereto to precipitate a crystal. The crystal was recovered by filtration and sufficiently washed with water, followed by drying to obtain 1.66 g of 2-(p-carboxyphenyl)-6-octylbenzothiazole (Yield: 95.7%).
