Trifluoroacetic acid → 3-(6-hydroxy-1,3-benzodioxol-5-yl)-1-pentyl-1,3-dihydro-2H-pyrrolo[3,2-c]pyridin-2-one

Participants

Reaction Steps

A mixture of 3-hydroxy-3-(6-hydroxy-1,3-benzodioxol-5-yl)-1-pentyl-1,3-dihydro-2H-pyrrolo[3,2-c]pyridin-2-one (0.15 g, 0.42 mmol), triethylsilane (1.60 mL, 10.0 mmol) and trifluroacetic acid (0.74 mL, 10.0 mmol) was stirred at ambient temperature overnight. The mixture was diluted with ethyl acetate (100 mL), washed with water, dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated in vacuo. The residue was triturated with diethyl ether to give the title compound as a white solid (not stable, turned to red in the air): MS (ES+) m/z 341.4 (M+1).
