Procedure

A suspension of NaH (1.25 g, 51 mmol, 60% in mineral oil) in DMF (47 mL) at 0° C. is treated with 5-methoxy-2-methylindole (500 mg, 3.1 mmol) and stirred at 0° C. for 0.5 h. The mixture is treated with HOSA (1.92 g, 17.0 mmol) portion wise and warmed to rt over 2 h. The mixture is then poured over ice, and extracted with EtOAc (3×50 mL). The combined organic layer is dried (Na2SO4), filtered and concentrated in vacuo to afford 5-methoxy-2-methyl-indol-1-ylamine, which is used in the next step without further purification.
