Procedure
Compound 411 (0.110 g, 0.000238 mol) dissolved in N,N-Dimethylformamide (3.72 mL, 0.0480 mol) and treated sequentially with N,N-Diisopropylethylamine (0.248 mL, 0.00143 mol) Acetic acid (0.0270 mL, 0.000476 mol) then N,N,N′,N′-Tetramethyl-O-(7-azabenzotriazol-1-yl)uronium Hexafluorophosphate (0.108 g, 0.000285 mol). Stir at r.t. overnight. Add sat. sodium bicarbonate, extract with ethyl acetate. Dried combined organics over sodium sulfate and concentrated. The crude product was purified by rHPLC to give 413. MS: (ESI+)=535.2. 1H NMR (400 MHz, DMSO) δ 8.37 (d, J=8.3 Hz, 1H), 8.15 (s, 1H), 7.93 (s, 1H), 7.89 (d, J=5.7 Hz, 1H), 7.42 (dd, J=8.2, 1.7 Hz, 1H), 7.28 (d, J=1.7 Hz, 1H), 7.18 (d, J=1.0 Hz, 1H), 6.17 (s, 1H), 5.15 (s, 1H), 4.91 (dd, J=17.5, 8.2 Hz, 1H), 4.71 (s, 1H), 4.51 (dd, J=16.3, 10.1 Hz, 2H), 4.36 (t, J=5.6 Hz, 2H), 4.20 (d, J=6.5 Hz, 2H), 3.39 (t, J=5.1 Hz, 2H), 1.23 (d, J=6.7 Hz, 3H), 1.09 (s, 6H)
