Versuchsvorschrift

At 0° C. to 115 mg 1-[6-(2,2,2-trifluoro-ethoxy)-pyridin-3-ylmethoxy]-naphthalene-2-carboxylic acid in 2 mL of abs. DMF 82 mg EDC, 45 mg 1-hydroxybenzotriazole and 49 mg N,N-diisopropylethylamine were added. After 30 min at 0° C. 56 mg of 2,2-dimethylglycine methyl ester hydrochloride and 49 mg N,N-diisopropylethylamine were added. The mixture was stirred for 16 h at room temperature. The mixture was poured into cold water, acidified to pH 3 with 2M HCl, extracted with ethyl acetate, washed with sat. sodium hydrogen carbonate solution and brine, dried over magnesium sulphate, filtrated and concentrated in vacuo to provide 124 mg of 2-methyl-2-({1-[6-(2,2,2-trifluoro-ethoxy)-pyridin-3-ylmethoxy]-naphthalene-2-carbonyl}-amino)-propionic acid methyl ester.
