実験手順
{3-[2-(3-Methoxy-benzyl)-1,1-dioxo-1,2-dihydro-1λ6-benzo[e][1,2,3]thiadiazin-4-yl]-5-fluoro-2-methyl-indol-1-yl}-acetic acid tert-butyl ester (61 μmol) was treated with TFA (2 mL) for 2 hours, concentrated, and purified by preparative LCMS to give the title compound. 1H NMR (d6-DMSO) δ 8.13 (d, 1H), 7.91 (t, 1H), 7.84 (t, 1H), 7.48 (d, 1H), 7.38 (dd, 1H), 7.28 (t, 1H), 6.91 (m, 4H), 6.69 (dd, 1H), 5.06 (bs, 2H), 4.51 (s, 2H), 3.71 (s, 3H), 2.11 (s, 3H) ppm. MS calculated for C26H22FN3O5S—H: 506, observed: 506.
