Reaction Steps

0.62 g (9.39 mM) of potassium hydroxide was dissolved in 30 ml of ethanol at 60°-65° C. To the solution, 1.50 g (3.48 mM) of 2-(4-hexylphenyl)-5-(6-acetoxynaphthalene-2-yl)-1,3,4-thiadiazole was added, followed by stirring for 10 minutes at 60°-65° C. The reaction mixture was poured into 100 ml of iced water and 0.83 ml of concentrated hydrochloric acid was added thereto to precipitate a crystal. The crystal was recovered by filtration and washed with water, followed by recrystallization from acetone to obtain 1.19 g of 2-(4-hexylphenyl)-5-(6-hydroxynaphthalene-2-yl)-1,3,4-thiadiazole (Yield: 87.9%). ##STR35##
