الإجراء التجريبي
1-(2-{4-[5-(2-Isobutyl-6-methyl-pyridin-4-yl)-[1,2,4]oxadiazol-3-yl]-phenyl}-acetyl)-azetidine-3-carboxylic acid methyl ester is prepared from {4-[5-(2-isobutyl-6-methyl-pyridin-4-yl)-[1,2,4]oxadiazol-3-yl]-phenyl}-acetic acid and azetidine-3-carboxylic acid methyl ester in analogy to Example 65; stirring this material in 3 N aq. NaOH/dioxane at rt for 20 h gives 1-(2-{4-[5-(2-isobutyl-6-methyl-pyridin-4-yl)-[1,2,4]oxadiazol-3-yl]-phenyl}-acetyl)-azetidine-3-carboxylic acid; LC-MS: tR=0.80, [M+1]+=435.02.
