Participants

Reaction Steps

To a solution of 6-hydroxy-6-(6-hydroxy-1,3-benzodioxol-5-yl)-4-pentyl-4,6-dihydro-5H-thieno[3,2-b]pyrrol-5-one (1.71 g, 4.70 mmol) in CH2Cl2 (30.0 mL) were added trifluoroacetic acid (6.00 g, 52.6 mmol) and triethylsilane (5.00 g, 43.0 mmol) at 0° C. The reaction mixture was stirred at ambient temperature for 16 hours and diluted with CH2Cl2 (50.0 mL). The mixture was washed with water (2×50.0 mL), dried over Na2SO4 and filtered. The filtrate was evaporated under reduced pressure. The residue was subjected to column chromatography to give the title compound (0.80 g, 49%) as a green solid: MS (ES+) m/z 346.4 (M+1).
