Versuchsvorschrift

To an N,N-dimethylformamide solution (6 ml) of 2′-{[(1R)-3-{[tert-butyl(diphenyl)silyl]oxy}-1-methylpropyl]oxy}-3-fluorobiphenyl-4-carboxylic acid (387 mg) were added at room temperature 7-chloro-3,3-dimethyl-1-piperidin-4-yl-3,4-dihydro-1,5-naphthyridin-2(1H)-one trifluoroacetate (Reference Example 10) (291 mg), diisopropylethylamine (0.497 ml) and 2-(1H-benzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (298 mg), followed by stirring overnight. The reaction solution was diluted with ethyl acetate, washed sequentially with a 10% aqueous citric acid solution, a saturated aqueous sodium hydrogen carbonate solution and saturated sodium chloride solution, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography to afford 1-{1-[(2′-{[(1R)-3-{[tert-butyl(diphenyl)silyl]oxy}-1-methylpropyl]oxy}-3-fluorobiphenyl-4-yl)carbonyl]piperidin-4-yl}-7-chloro-3,3-dimethyl-3,4-dihydro-1,5-naphthyridin-2(1H)-one (530 mg).
