Participants

Reaction Steps

To a solution of 5-hydroxy-3-(morpholin-4-ylsulfonyl)-1H-indole-2-carboxamide from Example 50 (37 mg, 0.12 mmol) in 3 mL of dichloromethane/acetonitrile (1:1) was added triethylamine (0.048 mL, 0.34 mmol) and methanesulfonyl chloride (0.0098 mL, 0.13 mmol). After one hour, another portion of methanesulfonyl chloride (0.005 mL) was added. After another 10 minutes, the mixture was partitioned between ethyl acetate and saturated NH4Cl solution, and the organic layer was washed with saturated NaHCO3 solution and brine, dried (Na2SO4), filtered, and concentrated in vacuo. The resulting solid was triturated with acetonitrile/methanol (1:1) to give the titled compound as a white solid. Proton NMR for the product was consistent with the titled compound. HRMS (ES) exact mass calculated for C14H18N3O7S2 (M+H+): 404.0581. Found 404.0620.
