Procedure

To a solution of 4-[6-((R)-2,2-dimethyl-[1,3]dioxolan-4-ylmethoxy)-naphthalen-2-ylmethoxy]-benzoic acid methyl ester (0.46, 1.09 mmol) in THF/water (10 ml of a 1:1 mixture) is added lithium hydroxide (0.15 g, 3.57 mmol). The reaction mixture is stirred at room temperature overnight, then at 70° C. for 24 h. The reaction mixture is cooled to room temperature, neutralized with 1.5 M HCl and the white solid obtained is collected by vacuum filtration, washed with water and dried under vacuum to afford 4-[6-((R)-2,2-Dimethyl-[1,3]dioxolan-4-ylmethoxy)-naphthalen-2-ylmethoxy]-benzoic acid. [M]− 407.
