Versuchsvorschrift

A stock solution of Example 14e and N,N-diisopropylethylamine (0.11 M and 0.33 M in N,N-dimethylacetamide, respectively, 350 μL, 0.038 mmol Example 14e and 0.11 mmol N,N-diisopropylethylamine), 2-(3H-[1,2,3]triazolo[4,5-b]pyridin-3-yl)-1,1,3,3-tetramethylisouronium hexafluorophosphate(V) (0.13 M in N,N-dimethylacetamide, 350 μL, 0.046 mmol), and 2-(4-chloro-2-fluorophenyl)acetic acid (0.40 M in N,N-dimethylacetamide, 113 μL, 0.050 mmol) were aspirated from their respective source vials, mixed through a perfluoroalkoxy mixing tube (0.2 mm inner diameter), and loaded into an injection loop. The reaction segment was injected into the flow reactor (Hastelloy coil, 0.75 mm inner diameter, 1.8 mL internal volume) set at 100° C., and passed through the reactor at 180 μL per minute (10 minute residence time). Upon exiting the reactor, the reaction mixture was loaded directly into an injection loop and purified by reverse phase HPLC(C8, acetonitrile/water (0.1% ammonium acetate), 5-100%) to yield the title compound as an impure mixture. The material was dissolved in methanol (1 mL) and manually injected into the HPLC(C8, acetonitrile/water (0.1% ammonium acetate), 5-100%) to give 0.0036 g (19%) of the title compound. 1H NMR (400 MHz, DMSO-d6/D2O) δ 8.52 (d, J=2.75 Hz, 1H), 8.43 (d, J=2.75 Hz, 1H), 7.76 (s, 1H), 7.47 (t, J=8.24 Hz, 1H), 7.42 (dd, J=9.77, 1.83 Hz, 1H), 7.30 (dd, J=8.09, 1.68 Hz, 1H), 7.07 (s, 1H), 6.87 (m, 2H), 6.58 (m, 2H), 4.61 (s, 2H), 4.05 (s, 3H), 3.82 (s, 2H).
