Diisopropylethylamine → HCID 178491801, 화합물

A stock solution of Example 23e and N,N-diisopropylethylamine (0.09 M and 0.25 M in N,N-dimethylacetamide, respectively, 450 μL, 0.2 mmol Example 23e and 0.6 mmol N,N-diisopropylethylamine), 2-(3H-[1,2,3]triazolo[4,5-b]pyridin-3-yl)-1,1,3,3-tetramethylisouronium hexafluorophosphate(V) (0.14 M in N,N-dimethylacetamide, 450 μL, 0.3 mmol), and 2-(5-fluoro-2-methoxyphenyl)acetic acid (0.40 M in N,N-dimethylacetamide, 125 μL, 0.24 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 min−1 (10 minute residence time). Upon exiting the reactor, the reaction mixture was loaded directly into an injection loop and purified using reverse phase HPLC(C8, acetonitrile/water (0.1% TFA), 5-100%) to give 0.0243 g (91%) of the title compound as the TFA salt. 1H NMR (400 MHz, DMSO-d6/D2O) δ 10.28 (s, 1H), 8.12 (d, J=2.44 Hz, 1H), 7.65 (s, 1H), 7.42 (dd, J=8.54, 2.44 Hz, 1H), 7.20 (d, J=8.54 Hz, 1H), 7.11 (m, 2H), 7.04 (s, 1H), 7.01 (m, 1H), 6.83 (m, 2H), 6.48 (m, 2H), 5.02 (d, J=15.56 Hz, 1H), 4.18 (d, J=15.87 Hz, 1H), 4.04 (s, 3H), 3.79 (s, 3H), 3.70 (s, 2H).
