Tetrabutylammonium Fluoride Trihydrate → HCID 86642678, compound

Participants

Reaction Steps

To a solution of (E)-butyl 3-[1-(triisopropylsilyl)-1H-pyrrol-3-yl]acrylate (10.0 g, 28.7 mmol) in 200 mL of THF was added tetra-n-butylammonium fluoride trihydrate (7.5 g, 23.8 mmol, 0.83 equiv.) at room temperature under N2. The solution was stirred for 30 min at room temperature, diluted with EtOAc (500 mL), and washed with water (2×100 mL). The organic layer was dried over Na2SO4 and concentrated under vacuum. The residue was applied onto a silica gel column, which was eluted with EtOAc/petroleum ether 1:5 to afford (E)-butyl 3-(1H-pyrrol-3-yl)acrylate (4.0 g, 72%) as a light yellow solid. LC-MS (ESI) m/z 194 (M+H+).
