With diethyl cyanophosphonate; triethylamine; In DMF (N,N-dimethyl-formamide); at 0 - 20℃; for 18.0h; | 67 mul of triethylamine, 34 mg of <strong>[13031-62-4]4-aminobutyric acid amide hydrochloride</strong> and 38 mul of cyanophosphonic acid diethyl ester are added in succession to 128 mg of 5(S)-tert-BUTOXYCARBONYLAMINO-4(S)-TERT-BUTYLDIMETHYLSILYLOXY-7(S)-isopropyl-2(R)-METHYL-8- [4-METHOXY-3-(3-METHOXY-PROPYLOXY)-phenyl]-octanoic acid in 8 ml of dimethylformamide at [0C.] The reaction mixture is stirred for a further 18 hours at room temperature. The reaction mixture is concentrated by evaporation and 20 ml of [10%] citric acid solution and ice are added to the residue. The mixture is extracted repeatedly with ethyl acetate and the organic phases are then washed with saturated sodium hydrogen carbonate solution and saturated sodium chloride solution. After concentration by evaporation, the residue is purified by means of FC (70 g of silica gel, dichloromethane/methanol=9: 1). The title compound is obtained: Rf (dichloromethane/methanol=9: 1) =0.38. |

With sodium methylate; In methanol; ethanol; isopropyl alcohol; | (B) 4-[(5-Chloro-2-hydroxy-3-methylphenyl)-(4-isopropylphenyl)-methylene]amino}-butanamide. 6 g (0.02 mol) of (5-chloro-2-hydroxy-3-methylphenyl)-(4-isopropylphenyl)-methanone, 3.86 g (0.031 mol) of gamma-aminobutyramide hydrochloride, 5.61 ml of a 30% solution sodium methoxide in methanol, 100 ml of methanol and 200 ml of ethanol are introduced into a 500 ml flask. This mixture is heated to 60 C. and then evaporated in vacuo. 300 ml of isopropanol are then added, the mixture is heated at the boiling point for 4 hours and then evaporated to dryness. The residue is washed with water and extracted with CH2 Cl2, and the methylene chloride solution is washed with water, dried and evaporated. The residue is recrystallized from ethyl acetate. Melting point of the product is 168-169 C. |

91% | With N-ethyl-N,N-diisopropylamine; In N,N-dimethyl-formamide; at 60℃; for 1.25h; | General procedure: To a solution of phenyl {3,5-difluoro-4-[(1 -[2-(trimethylsilyl)ethoxy]methyl}-1 H-pyrrolo[2,3- b]pyridin-4-yl)oxy]phenyl}carbamate (100 mg, 195 muetaetaomicronIota, intermediate 146) in DMF (I .O mL) was added 2-(piperidin-1 -yl)ethanamine (LOO eq., 25.1 mg, 195 mueta"omicronIota) and this mixture was stirred at 60 C for 75 minutes. After cooling to room temperature ethylacetate and water were added to the reaction mixture and the phases were separated. The aqueous phase was extracted two times with ethylacetate, the combined organic phases were washed with brine, dried over sodium sulfate, filtered and concentrated to dryness. The resulting residue was purified by flash chromatography (dichloromethane/ methanol) to give the title compound (1 10 mg, 95%). LC-MS (method 2): Rt = 1 .51 min; MS (ESIneg): m/z = 544 [M-H] This intermediate was prepared in analogy to intermediate 147 by reacting phenyl {3,5- difluoro-4-[(1 -[2-(trimethylsilyl)ethoxy]methyl}-1 H-pyrrolo[2,3-b]pyridin-4-yl)oxy]phenyl}carba- mate (100 mg, 195 muetaetaomicronIota, intermediate 146), <strong>[13031-62-4]4-aminobutanamide hydrochloride</strong> (1 :1 ) (1 .00 eq., 27.1 mg, 195 mueta"omicronIota) and additionally N,N-diisopropylethylamine (2.0 eq., 68 muIota_, 391 muetaetaomicronIota) in DMF for 75 minutes at 60 C to give after flash chromatography (dichloromethane/ methanol) the title compound (96 mg, 91 %). LC-MS (method 2): Rt = 1 .26 min; MS (ESIpos): m/z = 520 [M+H]+. |
