Reaction Steps

To a solution of 0.0738 g (0.157 mmol, 1.0 equiv.) of 3-(3-t-butyldimethysilyloxypropyl)-2-trimethylsilyl-N-methyl-1H-indole-5-methanesulfonamide in 2 mL of pyridine at 0° C. was added 1 mL of 48% aqueous hydrofluoric acid. The solution was stirred for 20 minutes at 0° C. The solution was diluted with 25 mL of ethyl acetate and washed with 10 mL of 10% aqueous sodium carbonate. The organic layer was dried over anhydrous sodium sulfate, filtered and concentrated in vacuo to yield 0.0551 g (99%) of 3-(3-hydroxypropyl)-2-trimethylsilyl-N-methyl-1H-indole-5-methanesulfonamide, homogeneous by 1H NMR and TLC.
