Reaction Steps
Palladium on carbon (25 mg) was placed under an inert atmosphere and suspended in 1:1 v/v EtOH/THF (10 mL). A solution of 5-nitrobenzo[b]thiophene 1,1-dioxide (250 mg, 1.18 mmol) in EtOH/THF (1:1) was then added, and the reaction mixture placed under H2 atmosphere (1 Atm pressure) and stirred at RT for 3 h. Reaction is filtered through a Celite pad and washed well with MeOH to obtain the title compound (200 mg, 92%) as a brown solid: TLC (10% MeOH/DCM w/5% NH4OH), Rf=0.40; LC MS m/z 184.1 (MH+).
