Next, 7.6 g of the 5-(1-adamantylethynyl)isophthalic acid dipotassium salt obtained above (19 mmol) was dissolved in 20 mL of ion-exchange water and filtered to remove insoluble matter. Then, 5 mol/L hydrochloric acid was added to a resulting filtrate with agitating so as to have pH of 1. Solid precipitate was collected by filtration, then washed with 50 mL of ion-exchange water and dried under reduced pressure, thus obtaining 6.1 g of 5-(1-adamantylethynyl)isophthalic acid (18.9 mmol; yield: 99.5%).
