Procedure

A solution of 290 (40 mg, 0.084 mmol) and 2-phenylacetyl isothiocyanate (22 mg, 0.126 mmol) in THF (2 mL) was stirred for 30 min. The solvent was removed under reduced pressure and the residue was purified by flash column chromatography (eluent EtOAc), to afford a solid material, which was dissolved in a mixture of TFA/DCM (0.5 mL/0.5 mL) and stirred at room temperature for 2 h. Solvents were removed under reduced pressure and the residue was purified by preparative HPLC (Aqusil C18, gradient eluent, 60-95% MeOH in water, 45 min) to afford the title compound 291 (8 mg, 80% yield) as an off-white solid. 1H NMR (d-DMSO) (ppm): 9.27(d, 1H), 8.57(d, 1H), 8.37(s, 1H), 8.30(s, 1H), 8.01(d, 1H), 7.53(m, 2H), 7.33-7.31(m, 4H), 7.29-7.25(m, 1H), 6.74(d, 1H), 4.46(m, 1H), 3.82(s, 2H), 3.11-3.03(m, 2H), 2.18-2.09(m, 2H), 1.93-1.89(m, 2H). MS (m/z): 550.2(M+H) (found).
