Versuchsvorschrift

To a solution of 36.3 mg (55.26 μmol) 3-(2′,2″-Diisobutyl-4-methoxycarbonylmethoxy-3-naphthalen-1-ylmethyl-[1,1′:4′,1″]-terphenyl-4″-yl)propionic acid methyl ester (79) in 8 ml 1.4-dioxane 2.0 ml (16.60 mmol, 301 eq.) 25% aq. NaOH-solution and 2.0 ml (3.08 mmol, 56 eq.) 40% aq. solution of Bu4NOH were added. The resulting mixture was refluxed for 24 h and then cooled to 0° C. Acidification to pH 1 by adding 1 N aq. HCl-solution led to a white precipitate which was obtained by filtration. A filtration over silica gel with EtOAc/HOAc (95+5)) as an eluent and a following lyophilization of the obtained oily product from a solution in CH3CN and aq. NH3-solution yielded 36.6 mg (55.2 μmol, 100%) of the bisammonia-salt of 3-(4-(Carboxymethoxy)-2,2″-diisobutyl-3-naphthalen-1-ylmethyl-[1,1′:4′,1″]-terphenyl-4″-yl)propionic acid (80) as a white solid.
