3-(morpholin-4-ylsulfonyl)-7-nitro-1H-indole-2-carboxamide → 7-Amino-3-(morpholin-4-ylsulfonyl)-1H-indole-2-carboxamide

Participants

Reaction Steps

To a solution of 3-(morpholin-4-ylsulfonyl)-7-nitro-1H-indole-2-carboxamide (708 mg, 2.00 mmol) in 30 mL of methanol was added 10% palladium on carbon (200 mg), and the reaction was equipped with a balloon of hydrogen gas. After 2 hours, the reaction was filtered through celite, the filter pad was rinsed with ethyl acetate, and the resulting solution was concentrated in vacuo to provide the titled compound as a yellow solid. A portion of this was taken up in dichloromethane, treated with excess ethereal HCl, and concentrated in vacuo to give an off-white solid, used for biological testing. HRMS (ES) exact mass calculated for C13H17N4O4S (M+H+): 325.0965. Found 325.0971.
