Procedure

A solution of 1,2-dimethyl-5-nitro-1H-indole (500 mg) in 1:1 THF:methanol (10 mL) was treated with 10% palladium on carbon (100 mg), stirred under hydrogen (1 atm) for 1 hour, filtered through diatomaceous earth (Celite®), and concentrated. The crude product was used without further purification in the next step.
