実験手順
Following the procedure of Example 26, pyridine (0.7 g, 8.35 mmol) and methanesulfonic anhydride (1.09 g, 6.26 mmol) were added to Compound 84 (1.07 g, 2.09 mmol) (prepared in Example 24) in THF (20 mL). The mixture was heated at 50° C. for 2 h, then cooled to rt. Another portion of THF (10 mL) was added, followed by addition of 1N HCl (10 mL). The mixture was stirred for 15 min, then extracted with EtOAc several times. The combined EtOAc layers were washed once with 1 N HCl (10 mL), water (2×20 mL) and saturated NaCl (20 mL), then dried (Na2SO4) and evaporated in vacuo to obtain a 3-[1-[3-[(methylsulfonyl)oxy]propyl]-1H-indazol-3-yl]-4-[1-(2-naphthalenyl)-1H-indol-3-yl]-1H-pyrrole-2,5-dione analog of Compound 26a (1.1 g, 92%) as a reddish solid. ES-MS m/z 591 (MH+).
