A 300-mL eggplant shaped flask was charged with 2.0 g of 2,4,6-tricyclohexylbenzoic acid (prepared in Synthesis Example 1-5), 0.5 g of sodium hydrogencarbonate, 10 g of methyl isobutyl ketone, and 10 g of water, which were stirred at room temperature. At the end of stirring, the reaction solution was concentrated, followed by twice of azeotropic dehydration with 30 g of methyl isobutyl ketone. To the solid precipitate, 30 g of acetonitrile was added, whereupon solid-liquid washing was conducted for 30 minutes. The solid was filtered and dried, obtaining the target compound, sodium 2,4,6-tricyclohexylbenzoate as white crystal. Amount 2.0 g, yield 90%.
