The experimental for Intermediate 5 Batch 1 was followed using OsO4 (27 mg, 0.11 mmol), 1-[(4-methylphenyl)sulfonyl]-4-vinyl-1H-indole (0.321 g, 1.08 mmol; Intermediate 4), 2,6-lutidine (0.251 mL, 0.23 mmol), dioxane (12 mL), sodium periodate (0.924 g, 4.32 mmol) and water (4 mL). The mixture was stirred for 20 min. and partitioned between 2M aqueous HCl (25 mL) and DCM (25 mL). The organic layer was dried, filtered, combined with Intermediate 5 Batch 1, and concentrated to give a total yield of 390 mg, 99% of a black solid. MS (ESI+) for C16H13NO3S m/z 300 (M+H)+.
