Procedure
{3-[2-(2-Chloro-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 8.18 (d, 1H), 7.94 (t, 1H), 7.83 (t, 1H), 7.45 (m, 6H), 6.88 (dt, 1H), 6.51 (dd, 1H), 5.19 (bs, 2H), 4.43 (s, 2H), 2.02 (s, 3H) ppm. MS calculated for C25H19FClN3O4S—H: 510, observed: 510.
